you: A non-answer.
Not a non-answer, just short-hand for the reasonably well-informed--I made the mistake of assuming you were in that category. Ansar al Islam, an Al Qaeda organization, was operating from an enclave in Iraq. At least one high level prisoner from Ansar al Islam also told of high level meetings with Hussein's government. Al Qaeda prisoners in Gitmo told of Iraqi support for training. Again, indicators.
me: [the war was based on]the nexus between Hussein's WMD programs
you: The ones which have yet to be found? Those weapons?
You're kidding right? It is beyond dispute except for the reality-challenged or the ideologically-blinded that Iraq had WMD. The only question is what happened to them.
his hostility to the US, Most of the world is hostile to us, shall we attack them all?
Look up the word "nexus" that precedes my quote above that you took out of context. It's the combination & connection of factors that count. Hostility toward the US was one of them
me: his unpredictability and willingness to use force (including WMD) in the past,
you: He was entirely predictable.
Read your history. He surprised the Iranians when he attacked. He surprised the Kuwaitis when he attacked. Nobody, not the USA or our allies, predicted those attacks. He used chem against the Iranians & his own people(since you deny Hussein had WMD, perhaps you could explain the thousands of deaths from chemical attacks?) He was unpredictable in 93 when he staged his force forward at the Kuwaiti border again. He attempted to assassinate a former U.S. President. The current and past two Presidents sure couldn't predict what he'd do or how he'd react to economic sanctions, diplomatic pressure, or missile & bombing strikes. I'm sure you would have done better.
me: and his unquestionable cooperation with terrorism in the past.
you: Which terrorism? Proof of terrorism against us please
Iraq was the home of the Abu Nidal organisation--ANO was responsible for the deaths of Americans in airport attacks and airplane hijackings. And Abu Abbas was captured by U.S. forces in Iraq--remember Leon Klinghoffer & the Achille Lauro? How about Abdul Rahman Yasin, the only 1993 World Trade Center bombing indictee not in prison--he escaped to Iraq. Hussein was paying for the suicide bombers in Palestine. 500 suicide bombing belts were found in a high school. etc etc Are you really this ignorant?
I'm not in the mood today to engage in a namecalling contest. Your points are all disputable but I'm going to move on because your namecalling and misrepresentaions of what I have said.
If you grow up, let me know and I'll be happy to point out where you are wrong.
