Here's MY key quote:

Mr. Kay's report contains powerful evidence that significant illegal weapons programs were not discovered by U.N. inspectors and that Saddam Hussein was aggressively violating U.N. Resolution 1441, which offered him "a final opportunity" to voluntarily disarm. The report says the team "discovered dozens of WMD-related program activities and significant amounts of equipment that Iraq concealed from the United Nations during the inspections that began in late 2002." These include "a clandestine network of laboratories" suitable for producing biological weapons; a prison laboratory that may have been used to test biological agents on humans; and strains of biological organisms concealed in a scientist's home. Most remarkable are multiple and extensive Iraqi programs for producing banned long-range ballistic missiles, one of which continued even while the inspectors were in Iraq.

The unclassified piece of Mr. Kay's report supports his conclusion that Saddam Hussein never abandoned his intention to produce biological, chemical and nuclear weapons and would have manufactured such weapons as soon as inspectors departed -- or, in the case of some weapons, even while they were in Iraq. It is also possible that some stocks of chemical weapons remain: In an interview on PBS's "NewsHour with Jim Lehrer," Mr. Kay said that "general officers" of the Republican Guard told his group that "their units were readied" to use chemicals against U.S. troops during the war, though the munitions have not been found.

For opponents of the war, Mr. Kay's report ought to raise the question of how the illegal and dangerous activity he has uncovered would have been stopped without military intervention, given Iraq's success in concealing it from inspectors.

But as I say, read the whole thing.

By the way, aggressive violation of 1441 was justification for the war all by itself.
