Yes, impeachment. And Cheney and Rumsfeld should be tried for crimes against humanity. Their unprovoked, lies-driven invasion of Iraq has caused countless deaths (over 100,000). Even today, there’s almost daily carnage there. All that chaos was unleashed by the real axis of evil: dubya-cheney-rumsfeld. Saddam was a crook and a dictator, but he was no madman, and he kept order in his country.
Now we are in a Catch 22: we are damned if we stay in the hell we created in Iraq, but if we leave, the Taliban-style fanatics will take over. Either way we are infinitely worse than had Saddam stayed in power. And hatred of the USA increases by the day, because of these injustices. This certainly makes us less secure, for decades to come. Satan (if he or she exists) should be very proud of this axis of evil (see above).
BTW: The 100,000 deaths are based on conservative and scientific estimates published by The Lancet, a highly respected British medical journal.
