„There is no military solution to this war. No amount of U.S. soldiers — not 10,000 more, not 20,000 more, not the almost 30,000 more that we now know we are sending– can solve the grievances that lay at the heart of someone else‘s civil war. Our troops cannot serve as their diplomats, and we can no longer referee their civil war.“ – Barack Obama, March 21, 2007
