This simple chart dramatizes something that I don’t think most Americans realize: the tripling of U.S. troops in Afghanistan by President Obama.

Now it’s true that when candidate Barack Obama vowed, “I will bring this war to an end in 2009,” he was talking about Iraq. In July 2008 he suggested that he would send two more brigades — about 8000 troops — to Afghanistan. He has far exceeded that, and we can only wonder whether the voters who responded to his antiwar message anticipated that he would increase the number of troops in Afghanistan by almost as much as he reduced the number in Iraq.
