Ok, I'll cut to the chase. Here are some specific proposals to deal with Saddam:
Continue to keep him in his "box" as long as he violates UN resolutions. The threat from Saddam is way overblown IMHO. North Korea has long range ballistic missles (something Saddam doesn't have), they are probably much further along in their nuclear program than Iraq, yet South Korea, Japan and the US are not beating the war drums against North Korea. Relations are getting better not progressively worst. That country is one of the most oppressive places in the world.
Radically alter our dependence on foreign oil. If W stood up to the big oil companies and to the Detroit lobby, we could dramaticall reduce our need for oil from OPEC, etc. Start by raising fuel standards on cars. Limit the gas guzzling SUV's. Create more incentives for companies to produce hybrid vehicles.
Why is Iraq forbidden from having WMD when other potentially dangerous and wild regimes (Syria, Libya, North Korea, Pakistan, etc) are allowed to have them? The UN needs to draw the line somewhere.
Continue to fund the Iraqi opposition groups.
The UN needs to figure out what the consequences are when their resolutions are violated. Of course, since Israel constantly thumbs its nose at UN resolutions, the US walks a very delicate line.
