Is Iran "the most active state sponsor of international terrorism"?

Glenn Greenwald asks that very relevant question because he fears that the Bush Administration is trying to mislead the nation into a war... again.

It is widely accepted, even by journalists, that the media failed to subject government pre-war claims about Iraq to sufficient scrutiny. The fact that even six months after the American invasion of Iraq, 70% of Americans were allowed to believe that Saddam personally planned the 9/11 attacks is, by itself, a rather conclusive testament to the profound failure of the media to inform citizens of the facts behind the government's claims.

That must not be allowed to happen again. If Americans want to initiate a military attack against Iran due in part or in full to Iran's support of Hezbollah's attacks against Israel, that is something they can decide. Plenty of other countries have gone to war before in defense of their allies. But the debate has to be honest and clear. Americans should not decide to attack Iran because the Bush administration is allowed to mislead them -- as they are clearly trying to do -- into believing that Iran (or Syria) is behind the terrorist threats against the United States. Iran has as much involvement in terrorist threats against the U.S. as Iraq had -- which is to say none at all -- and the administration cannot be allowed to get away with implying otherwise.
