It doesn't matter who the president is, kids. As long as he is the American president, there will be trouble.
Obama could get down on his hand and knees and lick the feet of Ahmadinejad and all the Iranian mullahs and it would not make a damn bit of difference. Their problem is with the West in general and America in particular. To these medieval mystics, Obama is still the president of the Great Satan and anything he is says will only be interpreted as "Western filth" and aggressive American "imperialism" and "interference".
There is no coming to terms with a violent pile of religious crazies.
