Very well, I will grant that the governments probably didn't know the intellegence was bullshit.

Iran is a different situation then Iraq, we had weapon inspectors in Iraq trying to find something but found nothing, we assumed they had some, we are assuming Iran want some, we actually know they are running a nuclear program, but not sure what for and since we can't trust Iran we have to assume the worst and stop them one way or another for our own saftey.
