It's possible it was in their airspace, but I don't see what our motivation would be to do that. Wars don't always win elections. Bush almost lost because of a war. If you want to win an election, make sure everyone has money in the bank. People tend to vote with their wallet.
Oh definitely agree that their wallet is #1 (and numbers like 2,3,4,5).
Bush was extremely popular post-9/11. He was extremely popular in the immediate aftermath of Iraq. He caught bad timing because by late 2004 that war had quickly become extremely unpopular.
I think Trump could really rally his base with a war against an islamic nation that is "threatening our national security".
