2012 US presidential election candidates Barack Obama and Mitt Romney took part Monday in their third and final presidential debate at Lynn University in Florida. The topic of the debate was foreign policy and the candidates discussed the Arab Spring, Iran, and Mali, among other issues.

Mr. Obama criticised Mr. Romney’s foreign policy positions as “all over the map”. “Every time you have offered an opinion you have been wrong.” “You said we should have gone into Iraq, despite the fact there were no weapons of mass destruction. You said we should still have troops in Iraq to this day. You said we shouldn’t be passing nuclear treaties with Russia.” Mr. Romney countered saying Mr. Obama had failed to take proper advantage of the Arab Spring: “I congratulate him on taking out Osama bin Laden and going after the leadership of al-Qaeda, but we can’t kill our way out of this mess”.

Mr. Romney said Mr. Obama was proposing military budget cuts. He said “the highest responsibility of the President of the United states … is to maintain the safety of the American people, and I will not cut our military budget by a trillion dollars… That in my view is making our future less certain and less secure”. Mr. Obama accused Mr. Romney of not properly understanding modern defense priorities. “You mention the navy, for example, and that we have fewer ships than we did in 1916. Well Governor, we also have fewer horses and bayonets. Because the nature of the military has changed. We have these things called aircraft carriers, where planes land on them. We have these ships that go underwater, nuclear submarines”.

Mr. Romney criticized his opponent for visiting the Middle East on an “apology tour”, and said he would be tougher with Iran. “I think from the very beginning, one of the challenges we’ve had with Iran is that they have looked at this administration and felt that the administration was not as strong as it needed to be. We’re four years closer to a nuclear Iran and we should not have wasted these four years.” Mr. Obama said he would stand with Israel against Iranian threats but added that the main national security concern was terrorist networks. He said his administration had focused on “those who actually killed us on 9/11” and said that under his leadership, “al-Qaeda’s core leadership has been decimated”. Mr. Romney said northern Mali had been taken over by “al-Qaeda-type individuals” .

Mr. Romney criticized China for “holding down artificially the value of their currency”. He added “on day one, I will label them a currency manipulator, which allows us to apply tariffs where they’re taking jobs.” Mr. Obama countered saying under Mr. Romney’s policy America would be “buying cars from China instead of selling cars to China”.

A poll, taken by CBS straight after the debate, indicated 53% of voters thought Mr. Obama had done better, while only 23% thought Mr. Romney had done better.

Both candidates now have plans for continued campaigning ahead of the election on November 6. Mr. Obama is to travel through Ohio, Florida, Virginia, Iowa, Colorado, and Nevada as well as appearing on The Tonight Show with Jay Leno in a two-day “America Forward Tour”. Mr. Romney is to hold two joint rallies with his vice-presidential candidate Paul Ryan in Nevada and Colorado before going on to campaign in Iowa and Ohio. Mr. Romney’s advisers said he would also consider making a speech on government spending and debt in the next few days.

India is the latest of the countries where the One Laptop Per Child (OLPC) experiment has started. Children from the village of Khairat were given the opportunity to learn how to use the XO laptop. During the last year XO was distributed to children from Arahuay in Peru, Ban Samkha in Thailand, Cardal in Uruguay and Galadima in Nigeria. The OLPC team are, in their reports on the startup of the trials, delighted with how the laptop has improved access to information and ability to carry out educational activities. Thailand’s The Nation has praised the project, describing the children as “enthusiastic” and keen to attend school with their laptops.

Recent good news for the project sees Uruguay having ordered 100,000 of the machines which are to be given to children aged six to twelve. Should all go according to plan a further 300,000 machines will be purchased by 2009 to give one to every child in the country. As the first to order, Uruguay chose the OLPC XO laptop over its rival from Intel, the Classmate PC. In parallel with the delivery of the laptops network connectivity will be provided to schools involved in the project.

The remainder of this article is based on Carla G. Munroy’s Khairat Chronicle, which is available from the OLPC Wiki. Additional sources are listed at the end.

NASA’s Cassini–Huygens spacecraft has discovered evidence for a large-scale saltwater reservoir beneath the icy crust of Saturn’s moon Enceladus. The data came from the spacecraft’s direct analysis of salt-rich ice grains close to the jets ejected from the moon. The study has been published in this week’s edition of the journal Nature.

Data from Cassini’s cosmic dust analyzer show the grains expelled from fissures, known as tiger stripes, are relatively small and usually low in salt far away from the moon. Closer to the moon’s surface, Cassini found that relatively large grains rich with sodium and potassium dominate the plumes. The salt-rich particles have an “ocean-like” composition and indicate that most, if not all, of the expelled ice and water vapor comes from the evaporation of liquid salt-water. When water freezes, the salt is squeezed out, leaving pure water ice behind.

Cassini’s ultraviolet imaging spectrograph also recently obtained complementary results that support the presence of a subsurface ocean. A team of Cassini researchers led by Candice Hansen of the Planetary Science Institute in Tucson, Arizona, measured gas shooting out of distinct jets originating in the moon’s south polar region at five to eight times the speed of sound, several times faster than previously measured. These observations of distinct jets, from a 2010 flyby, are consistent with results showing a difference in composition of ice grains close to the moon’s surface and those that made it out to the E ring, the outermost ring that gets its material primarily from Enceladean jets. If the plumes emanated from ice, they should have very little salt in them.

“There currently is no plausible way to produce a steady outflow of salt-rich grains from solid ice across all the tiger stripes other than salt water under Enceladus’s icy surface,” said Frank Postberg, a Cassini team scientist at the University of Heidelberg in Germany.

The data suggests a layer of water between the moon’s rocky core and its icy mantle, possibly as deep as about 50 miles (80 kilometers) beneath the surface. As this water washes against the rocks, it dissolves salt compounds and rises through fractures in the overlying ice to form reserves nearer the surface. If the outermost layer cracks open, the decrease in pressure from these reserves to space causes a plume to shoot out. Roughly 400 pounds (200 kilograms) of water vapor is lost every second in the plumes, with smaller amounts being lost as ice grains. The team calculates the water reserves must have large evaporating surfaces, or they would freeze easily and stop the plumes.

“We imagine that between the ice and the ice core there is an ocean of depth and this is somehow connected to the surface reservoir,” added Postberg.

The Cassini mission discovered Enceladus’ water-vapor and ice jets in 2005. In 2009, scientists working with the cosmic dust analyzer examined some sodium salts found in ice grains of Saturn’s E ring but the link to subsurface salt water was not definitive. The new paper analyzes three Enceladus flybys in 2008 and 2009 with the same instrument, focusing on the composition of freshly ejected plume grains. In 2008, Cassini discovered a high “density of volatile gases, water vapor, carbon dioxide and carbon monoxide, as well as organic materials, some 20 times denser than expected” in geysers erupting from the moon. The icy particles hit the detector target at speeds between 15,000 and 39,000 MPH (23,000 and 63,000 KPH), vaporizing instantly. Electrical fields inside the cosmic dust analyzer separated the various constituents of the impact cloud.

“Enceladus has got warmth, water and organic chemicals, some of the essential building blocks needed for life,” said Dennis Matson in 2008, Cassini project scientist at NASA’s Jet Propulsion Laboratory in Pasadena, California.

“This finding is a crucial new piece of evidence showing that environmental conditions favorable to the emergence of life can be sustained on icy bodies orbiting gas giant planets,” said Nicolas Altobelli, the European Space Agency’s project scientist for Cassini.

“If there is water in such an unexpected place, it leaves possibility for the rest of the universe,” said Postberg.

A script prepared by the British Broadcasting Corporation (BBC) and the Government of the United Kingdom in the 1970s, and released today, shows the text of the radio announcement that would be made in case of a nuclear attack on Britain.

The script was released by The National Archives, and it was discussed during the years from 1973 to 1975, as an act of preparation for a nuclear attack. This increased concern occurred due to the ongoing Cold War.

The script started by saying “This is the Wartime Broadcasting Service. This country has been attacked with nuclear weapons. Communications have been severely disrupted, and the number of casualties and the extent of the damage are not yet known. We shall bring you further information as soon as possible. Meanwhile, stay tuned to this wavelength, stay calm and stay in your own homes.” It emphasised people should not leave their homes: “Remember there is nothing to be gained by trying to get away. By leaving your homes you could be exposing yourselves to greater danger.”

“If you leave, you may find yourself without food, without water, without accommodation and without protection. Radioactive fall-out, which follows a nuclear explosion, is many times more dangerous if you are directly exposed to it in the open. Roofs and walls offer substantial protection. The safest place is indoors.”

The script continued by telling citizens to “make sure gas and other fuel supplies are turned off and that all fires are extinguished,” before telling the listener to “use your water only for essential drinking and cooking purposes.”

“Make your food stocks last: ration your supply, because it may have to last for 14 days or more,” continued the script. “If you live in an area where a fall-out warning has been given, stay in your fall-out room until you are told it is safe to come out.”

The script finishes people by telling people to turn off their radio to conserve energy.

The documents were released under Britain’s Freedom of Information Act, and it also said that all reports should be given out in an authoritative and comforting tone. It also contains letters from the Ministry of Posts and Telecommunications which describe how the use of a familiar voice will assure listeners that the BBC has not been obliterated.

Last week, RAF Leuchars in Fife scambled two Tornado F3 interceptors, when radar detected two Tupolev Tu-142 Bear Bombers and the alarm was sounded “Bears in the Air”.

The RAF would not disclose the exact time of the incident, which was to the north of the Outer Hebrides. It did say that no contact was made between the aircraft.

The Russian Bear Foxtrot bombers are renowned maritime raiders that regularly probed the United Kingdom’s airspace during the Cold War.

The Russian aircraft were snooping on Neptune Warrior, a Royal Navy exercise taking place near the Outer Hebrides last week. Neptune Warrior was a live-fire naval training exercise involving warships, submarines and aircraft that took place between April 22 and May 3.

The Tornado’s watched the Russians for approximately 15 minutes until the bombers returned to their home base in Murmansk.

During the Cold War in the 1970s and 1980s, Soviet spies were sometimes spotted watching from the perimeter of RAF stations to time exactly how long it took jets to take off and intercept Bear bombers, probing the United Kingdom’s defences and testing the response. Nato pilots in those days were well accustomed to an almost daily aerial game of cat-and-mouse.

Squadrons of Phantom interceptors were on constant quick-reaction standby through the 1970s and 1980s to deal with the threat of Soviet long-range bombers engaging in a long-range attack on Great Britain. The Bears can carry an arsenal of missiles, some nuclear-tipped, to strike NATO warships blocking the entrance to the vital North Atlantic sealanes between the United States and Europe.

In July, the Tornado will be replaced by the new Eurofighter Typhoon. Currently, RAF personnel on scrambling duty spend most of their time on counter-terrorist missions, checking out commercial airliners approaching Britain in ways that arouse suspicion, either because they have taken the wrong flight path or because the pilot has not contacted ground control.

The government of China has decided to stop its currency peg to the U.S. dollar. The country will revalue its currency, the yuan, for the first time in a decade. This comes after international pressure from Western countries, especially from the United States. The yuan will now be linked to a variety of different currencies.

The People’s Bank of China has announced a 2.1% revaluation increase which will allow the yuan to fluctuate +/- 0.3 yuan in daily trading. This means, like other currencies, that closing prices one day become opening prices the next day.

The U.S. government has been pressuring China to revalue its currency since China joined the WTO. The U.S. said that China has kept the yuan up to 40% under its real value to increase exports, thus giving China an unfair advantage against western industrial competitors as well as industry in developing nations.

Since the announcement the yuan has strengthened to 8.11 yuan to the US dollar instead of 8.28 as it has been for the last ten years. This means the yuan is more expensive and that Chinese goods will become more expensive in western countries.

Economic growth in China might also slow down, but it has been soaring for the last several years. This could have serious consequences in China, but a People’s Bank of China person has said that the exchange rate will be “basically stable”.

China linked the yuan to the dollar in 1997 during the major economic crisis in Asia. This has provided the stability which has allowed the Chinese economy to grow over the last ten years. This move will make China vulnerable to future financial fluctuations.

This move could also mean that the US dollar would fall if China switches from holding dollars to holding for example the euro or other strong currencies.

Four people from the NHS West Midlands in England have died after contracting the H1N1 swine flu virus. With these deaths, the number of people that have been killed in the West Midlands from the disease has now increased to 19.

NHS West Midlands has said that the number of people admitted to hospitals in the region with the disease this week was 203, whereas last week there were 146. It was also said that the number of inpatients taken into hospitals in the area was 95 from this Wednesday onwards.

Dr. Rashmi Shukla, the regional director of Public Health in the National Health Service, said about the incident: “We would expect to see a rise in respiratory illness, such as swine flu, at this time of year, and we would like to remind people that they should continue to adhere to good respiratory and hand hygiene practices to reduce chances of the virus spreading.

“Unfortunately there have been a further four swine-flu related deaths and our thoughts are with the families of these patients at this very sad time. The vaccination programme has started well across the West Midlands. It is very important that frontline health and social care workers in the West Midlands have this vaccine to protect themselves, their families and their patients.”

Beginning Monday morning, many BlueFrog and Blue Security users began receiving an email warning them that if they did not remove their email addresses from the Blue Security registry, they would begin to receive huge amounts of unsolicited email. As quickly as four hours after the initial warning message, some users began to receive an unprecedented amount of spam. Most of the messages were simply useless text. Users reported that Blue Security’s website was unavailable or extremely slow in responding.

Blue Security is an online community dedicated to fighting spam. As they became more popular, their member list increased substantially. The members’ email address is encrypted and added to a list of e-mail addresses that wish to stop receiving spam. Blue Security maintains the encrypted list, which uses an encrypted hash function. Spammers are encouraged to remove all addressed from their email list that are also in Blue Security’s Do Not Intrude Registry by using free compliance tools available at Blue Security’s web site.

According to Blue Security’s web site, “A major spammer had started spamming our members with discouraging messages in an attempt to demoralize our community. This spammer is using mailing lists he already owns that may contain addresses of some community members.” Reportedly, Blue Security has received complaints from users about spam allegedly sent from Blue Security promoting their anti-spam solution and web site.

Blue Security states they are “an anti-spam company determined to fight spam and as such never has and never will send unsolicited email.” There are also reports of non-users of BlueSecurity/BlueFrog receiving the warning emails, which now seems is also being sent to email addresses of people who have never added their email address to Blue Security’s Do Not Intrude Registry.

The United Nations High Commissioner for Refugees (UNHCR) called on the international community to increase aid and assistance to the two countries shouldering the bulk of displaced Iraqis. Syria and Jordan have received the largest number of Iraqi refugees and are having difficulty coping with the numbers.

The appeal was made by UNHCR spokesman Ron Redmond at a press conference on Friday at the Palais des Nations in Geneva, Switzerland. He criticized governments for earlier expressing concern and pledging support for the refugees but not following through on promises. “Syria and Jordan have still received next to nothing in bilateral help from the world community,” said Redmond.

There are an estimated 2 million Iraqi refugees total in Syria and Jordan with the numbers increasing daily. Each day, Syria receives approximately 2,000 Iraqis and, of those, about 1,000 will stay for an extended time. There are a further 2 million displaced Iraqis who move and settle in safer areas within Iraq.

The large numbers of refugees is putting pressure on the infrastructure of the host countries, resulting in difficult living conditions for the inhabitants. Ron Redmond acknowledges that some US$70 million in donations have been received by the UNHCR, and a further $10 million promised since the Iraq displacement conference in April, 2007. He points out, however, that much more is required. “We stressed then and we say it again, donors must provide direct bilateral support to these host countries whose schools, hospitals, public services and infrastructure are seriously overstretched because of the presence of millions of Iraqis they have so generously welcomed,” said Redmond.

Schools are particularly difficult to set up and staff in a refugee situation. Syria has currently hundreds of thousands of Iraqi refugee children, but only has resources for 32,000 students. Syria offers free access to public schools for refugees, but doesn’t have the infrastructure to cope. Some 14,000 Iraqi refugee children in Jordan attend school, out of the possible 250,000. The refugee children in Jordan don’t have access to public schools and instead go to private schools. UNHCR is partnering with UNICEF to provide 150,000 classroom spots in Syria, Jordan and Lebanon, but the coordination of the required resources, such as buildings, teachers, and school supplies is proving difficult.

Health issues for the refugees is also a concern. UNHCR has set up three primary care medical facilities in Syria, with two more in the works. But approximately 10,000 Iraqis per month require a doctor’s attention, 3,000 of which require serious medical treatment.

“It is unconscionable that generous host countries be left on their own to deal with such a huge crisis,” said Ron Redmond at the press conference. “We strongly urge governments to step forward now to support them in dealing with this situation and renew our call for international solidarity and burden sharing.”

The president of Refugees International, Ken Bacon, agrees that a more comprehensive approach to the situation is required and believes that it would be good investment for the United States to increase its aid to the region. “The United States ought to be pumping money into Jordan and Syria,” Bacon suggests. He feels that the sheer numbers of refugees can have a destabilizing influence in the Middle East. However, the complicated diplomatic relationship between the U.S. and Syria has resulted in slow progress, according to Bacon, as bilateral discussions have not taken place and the UN is forced to mediate.

Both Jordan and Syria have put in place new entry and residency conditions, which has resulted in thousands of refugees being stranded on Iraq’s borders. Families have been separated based on a person’s age and type of passport held. Jordan and Syria have not signed on to the UN Convention Relating to the Status of Refugees.

The non-governmental organization Human Rights Watch has been critical of Jordan and Syria on their policy of returning refugees, saying they “are violating on a daily basis the most fundamental principle of refugee protection – nonrefoulement, which prohibits the return of refugees to persecution or serious harm.”

To gain access to Jordan, Iraqi refugees must be over 40 or under 20, and must prove they have sufficient funds to support themselves in the country. They must also be in possession of a new generation passport.

Nasser Hikmat Jaafar drove 900 km from Baghdad with his family to reach Jordan in mid-June, 2007. Half of his family was refused entry to Jordan. “They allowed entry just for my wife and two daughters and denied me and my three sons. They didn’t tell us the reasons, but just said they are fed up with men of such ages [between 20 and 40 years old],” said Jaafar. He changed plans and traveled with all his family to the Syrian border, a distance of approximately 500 km from Iraq’s Jordanian border.

Syria has less restrictions on gaining entry, but has imposed residency conditions. Refugees can only stay up to three months and must then leave Syria and re-enter to be eligible to stay for another period.

The United States government has a program set up for Iraqi asylum seekers in Jordan who meet specific criteria. If they meet the requirements, listed below, they may be eligible for resettlement under the United States Refugee Admissions Program (USRAP).

Interested asylum seekers are encouraged to apply directly with the U.S. Overseas Processing Entity (OPE) in Amman, Jordan, which is operated by the International Organization for Migration (IOM). Individual Iraqis and their immediate family that meet one of the conditions below may seek access through the direct program:

• Individuals who worked on a full-time basis as interpreters/translators for the U.S. Government or Multi-National Forces (MNF-I);
• Locally Employed Staff (LES) engaged by the U.S. Government under the authority of the Chief of Mission or the Coalition Provisional Authority (CPA); or
• Surviving immediate family members of interpreters/translators or LES.

According to the U.S. government information on the process, those individuals initiating a case with the OPE will not be guaranteed an interview for resettlement in the United States. Applicants would be screened for eligibility as per the requirements listed above and are subject to approval.

In a February 14, 2007 press briefing, U.S. Under Secretary for Democracy and Global Affairs Paula J. Dobriansky addressed the Iraq refugee crisis. “Our key immediate objectives are to assist internally displaced Iraqis and Iraqi refugees by building up the capacities of UN agencies and NGOs,” said Dobriansky. “This includes increasing opportunities for permanent resettlement for the most vulnerable Iraqis, to establish specialized programs to assist Iraqis who are at risk because of their employment or close association with the United States Government, to work diplomatically with regional governments through bilateral and multilateral channels to uphold the principle of first asylum,” she continued.

In the February press briefing, the U.S. committed to receive 7,000 Iraqi refugees by fiscal year end, September 30, but clarified that perhaps only half that number would be “travel-ready” subsequent to the interview process as described above. The U.S. could accommodate 20,000 to 30,000 Iraqi refugees per year without difficulty, according to Ken Bacon of Refugees International.

To date, the U.S. has allowed 750 Iraqi refugees into the country.
