The U.S. isn't known to retaliate just because someone got elected.
I have to respond on this point. Just look at an earlier 9/11 for a salient example,
11 September 1973.
Retaliation and intervention is what powerful nations do, all the time, throughout history. Many of the conflicts and tensions in the world since WW2 have been due to US involvement overseas. But this is not a problem with
the US, it's just that the US is the most powerful nation at present. Go back a hundred years, it was the UK and France doing all this stuff. Go back further, the Spanish in Central and South America.
