The most likely scenario if Israel attacks Iran before Election Day:
Obama gives the minimal possible assistance possible to the Israelis and then rides that scanty assistance to four more years in the White House, with the loving assistance of the Mainstream Liberal Media.
I don’t believe that Israel attacking before or after the election is anything most of the electorate cares about.
I think most of us are weary of the wars and to the point that if the Middle East wants to annihilate itself please go ahead.
