International politics is like highschool. Gossip and insults and 'wars' and all that stupid crap. When you were in highschool, did you beat up everyone who called you gay or stupid? I think not.
And as for Ahmadinejad calling Obama a wuss. Obama didn't have to kill his own people to get them to accept he won an election. So as far as im concerned AHmadinejad is the wuss and wont accept the possibility that maybe he lost.
And another thing! Obama saying that if we meddle they will use that against us is completely true. They will use that as an excuse to crackdown on protesters (which theyre doing,without us meddling), and an excuse to proliferate anti-US sentiment. This also brings us back to the avoiding conflict point.
