I think this a link you should look into–even though this subject is about 2 years old I think it’s worthy to ask questions of our government such as : Even if the “British told us first,” why was our govt relying on foreign intelligence without seeing the documents for ourselves? Why was this information (clearly unverified) used in President Bush’s State of the Union address and included in the President’s Daily Brief, a document that is highly classified? Why was this information used by Colin Powell in his address to the Senate shortly which shortly after mobilized the Democrats to join rank in the war cause?
Now that the Rove controversy has come to light, I think that these are all worthy questions and perhaps there is a “larger” body of evidence against Iraq (or was) but it seems that there are alot of dirty politics going on, and many were not going to let anyone get in their way of warring with Iraq.

I suspect the reason was speed and difficulty of detection.

It won’t make any difference to the left. They will continue to hang their whole case on the lack of finding of large stocks of ready to use WMD’s, even after two WMD weapons were used against us (sarin and mustard gas, both used incorrectly and hence not effectively), and the fact that Bush did’t say that the war was being fought because of any imminent threat, and the means to make both chem and bio weapons were found, the scientists are still afraid to talk and a number have been murdered post-war, and we havae found evidence of an active bioweapons research program, and facilities (including the Bacillus Thuringensis plant) that could rapidly produce sufficient amounts of bioweapons.

Nobody expected him to be able to quickly make a bomb, unless he bought appropriate material from out of the country (which, of course, we now know he could have – from A. Q. Kahn’s network).

…he could just have been in a hurry, as they say in the above link, which also seems to very effectively support your thesis.

Now, where did that “no imminant threat” mantra come from, anyway? Since he wouldn’t be a “real” danger for a couple of years yet, we could have waited till he could have done some real damage to our troops.
