The blogsphere and the mainstream media has been abuzz by Senator Obama seeming to state that he would invade Pakistan. While that is not quite what he said, he did state that he would strike inside Pakistan without the approval of the Pakistani government if there was a high priority target.
This is not entirely new for Obama. He had in his 2004 Senate race discussed the possible need for "surgical strikes" against Iran to stop their nuclear program. This has set off the usual rioting in Pakistan complete with burning American flags.
