Britain's Prime Minister David Cameron wife Samantha Cameron and US First Lady Michelle Obama served food to military personel during an event to honor military families from US and Britain service members and veterans at the 10 Downing Street in London, on May 25, 2011. Obama and his wife Michelle enjoyed a regal welcome from Queen Elizabeth II, who has met every US president but one since the 1950s. Obama's visit, the second stop on a European tour, comes as Britain seeks to prove its staying power despite fading military might and Washington looks to retool its decades-old alliance with Europe as a catalyst for global action.
