Ahmadinejad is a jerk, a loudmouth and a demagogue no doubt about it, but who cares?
If Iran hates us, we brought it on ourselves by sticking our noses into their business for decades, starting with overthrowing their democracy and
putting a puppet dictatorship in place back in 1953.
If they threaten Israel - who cares?
The Israelis have created their own problems.
Israel
is not the United States, and Israel should defend itself without our help.
As far as nukes go - even the US Government says they ended their weapons program five years ago...
Iran is not any kind of realistic military threat to the US.
As for terrorism - yes, we do support terrorist organizations fighting the Iranian government.
It's nothing new, we've supported terrorist movements for at least fifty years ... we just call them "freedom fighters"
