Iran today is responding to Obama. Unlike you and Obama, Iran knows Bush is no longer in office. Look it up.
Mind you, I am not a Bush supporter. He was a mediocre president. But, he was still better than the one after him. Probably better than the one before him too.
Clinton is well remembered because he had to bow to a Republican Congress.
But still, Bush was no Reagan. Barely better than Nixon, and certainly not an Eisenhower or even a Calvin Coolidge.
