German Chancellor Angela Merkel autographs a sigh held by a young girl welcoming US President Barack Obama to the eastern German city of Dresden on June 5, 2009. After policy talks and a news conference in Dresden, Obama and Merkel are due to travel to Buchenwald, the former Nazi concentration camp where more than 56,000 prisoners died in horrendous conditions. Obama today swaps the political heat of the Middle East for a solemn two-day mission of World War II remembrance, and a fresh round of transatlantic diplomacy.
