At a press conference conference in Warsaw on Tuesday, Secretary of State John Kerry appeared to briefly nod off to the dulcet sounds of his translator earpiece. To make things more awkward for Kerry, he was in the audience of a press conference conducted by his boss, Barack Obama. At least Kerry fell asleep during Polish President Bronislaw Komorowski's response to a question.

 The joint press conference launched Obama's European tour this week, during which Obama announced a $1 billion plan to increase American military deployments to Europe: "Our commitment to Poland's security as well as the security of our allies in central and eastern Europe is a cornerstone of our own security and it is sacrosanct," Obama said. The president more directly addressed the Ukraine crisis on Tuesday, saying that if Putin was willing "I think it is possible for us to try to rebuild some of the trust that has been shattered," but that such a move would take "quite some time," as CNN reported. 
 
 Aside from that brief nap, Kerry was actually pretty busy in Poland today: ||||| Polish leaders praised President Barack Obama on Saturday for pushing ahead on issues of key importance to Warsaw: establishing a U.S. military presence in this central European country and making it easier for Poles to visit the United States.

 As Obama wrapped up his first visit to Poland, the White House said the U.S. plans to establish an Air Force detachment of U.S. F-16 fighter jets and C-130 Hercules aircraft in Poland in 2013. 
 
 "I believe a new stage is opening in Polish-U.S. relations, also in the area of the U.S. military presence in Poland," Polish President Bronislaw Komorowski said in an interview after Obama's visit. 
 
 Poland and the U.S. are NATO allies and already cooperate closely, but Poland wants a stronger U.S. military presence on its soil as a way of enhancing its security. 
 
 "The order of magnitude is not really large, but the gesture is very significant," Polish Prime Minister Donald Tusk said at a joint news conference with Obama. 
 
 An analyst said having American "boots on the ground" has as symbolic aspect but that it's importance goes beyond that. "It means the commitment is larger than the commitment through NATO," said Marcin Zaborowski, director of the Polish Institute of International Affairs. 
 
 Obama also said he backs legislation sponsored by several members of the U.S. Congress that could ease travel restrictions for Poles _ a key issue in Polish-U.S. ties. 
 
 Obama noted that Poland currently does not meet criteria to enter the visa waiver system, and that "I could not simply waive the law." But he said the legislation he backs would change the criteria and should "resolve this issue in a way that is satisfactory to Poland but also meets the security concerns of the United States." 
 
 To a Polish reporter who asked when Poles could expect to shop on Fifth Avenue in New York, Obama said: "We very much want you to shop on Fifth Avenue and anywhere else in the United States." 
 
 President Komorowski said he felt "great satisfaction" that Obama presented "specific ideas for solving this problem that unnecessarily burdens Polish-American relations." 
 
 Currently, Poles must have a visa to enter the United States, a source of much dissatisfaction for years now. Many Poles feel they should have earned the right to visa-free travel to the U.S. given the nation's strong alliance with the U.S. and its support for the wars in Iraq and Afghanistan. 
 
 "The issue of visas exemplifies that there is a lack of reciprocity in this relationship. ... If you can't travel there (without a visa) you feel kind of humiliated," said Zaborowski. He added that while Poles will welcome Obama's promise to push the matter in Congress, ultimately Poles will judge him on the results.

 Monika Scislowska contributed to this report. ||||| Language problems between Russian air traffic controllers and Polish pilots, and pressure from high-ranking plane passengers, may have contributed to the crash on Saturday in which 96 people – including the Polish president – were killed, it was revealed today. 
 
 The Russian air traffic controller Pavel Plusnin – who was the last person to talk to the crew of President Lech Kaczynski's Tupolev 154 before it crashed – said he had difficulties understanding the crew who he said spoke poor Russian. 
 
 "Numbers were hard for them so I could not determine their altitude," he told a Russian news portal. But Poland's former prime minister told the Guardian he thought Kaczynski – who was determined to reach Smolensk where he was due to attend a memorial service on the 70th anniversary of the Katyn massacre – may himself have contributed to the accident by pressuring the pilots to land in dense fog. 
 
 The former social democrat prime minister Leszek Miller said: "The president had wanted so much to be there. The pilot knew this and so they accepted the risk and in the process they lost everything," he said. He said Poland would struggle to replace the victims, who included dozens of senior officials. "When people die, it's often said they're irreplaceable," he said. "But in this case I really believe it is going to be very hard to find people to take the places of these talented people." 
 
 Accident investigators have ruled out technical problems in the 26-year-old aircraft which crashed into dense trees, and yesterday said human error was to blame. Poland's chief prosecutor Andrzej Seremet said from initial interviews held with air traffic controllers, investigators had "concluded there were no conditions for landing". The plane tried to land despite being advised by air traffic control "not to do so" he said. 
 
 Seremet added that flight recordings would be listened to closely to determine whether the pilots came under pressure from the presidential entourage to continue with the landing. But he stressed "at present there is no such information". As investigators continued to probe the cause of the accident, an increasing number of Poles were asking how so many senior figures – including the country's entire military chiefs of staff, the head of national security, the head of the national bank, many of the government's top advisers and 18 MPs – had been allowed to travel on a single aircraft. 
 
 "How is it possible that all these top people came to be travelling on the same plane?" military expert Wojciech Luczak said. Acting President Bronislaw Komorowski, a member of prime minister Donald Tusk's centrist Civic Platform (PO) who had been expected to beat the rightwing Kaczynski in October's scheduled presidential election, moved yesterday to start replacing some of the officials who died in the crash. 
 
 "The first task I am going to set for the new National Security Bureau chief is a review of the rules for travel of top military officials," he told reporters. Meanwhile, in Moscow the process of identifying the remaining 95 bodies continued. Only 14 bodies had been immediately identifiable after the crash. Most of the other victims had been too badly charred and are being identified through DNA testing. Nine bodies are still missing. Polish military planes were due to be dispatched to Moscow to bring back the victims' bodies by Thursday at the latest. Kaczynski's body, which was returned to Warsaw on Sunday, will lie in state in Warsaw from today until a state funeral is held on Saturday, possibly as a joint service for all 96 victims. 
 
 Polish workplaces observed a minute's silence yesterday, while many of Warsaw's school pupils were allowed to visit the presidential palace to sign books of condolence.Komorowski, the interim president, said he wanted the funeral, which is due to be held on Warsaw's Pilsudski Square, to be an "expression of national unity".
– It's not that weird that a 70-year-old man traveling overseas and working long hours to boot would nod off at an inappropriate time. But when it happens to be Secretary of State John Kerry while attending a news conference with President Obama and Polish President Bronislaw Komorowski, the cameras are bound to notice. As ABC's did here. At least the brief power nap came during the Polish president's answer, notes the Wire.
