Now they're trying sarin gas. The chemical payload in the roadside bomb, detonated safely by American troops, is being reported as a 155-millimeter artillery shell. One of Saddam's, perhaps? Or Syria's? Or Iran's? Let there be no mistake: if our enemies had more than an artillery shell's-worth, they'd use it, and they'd use it on American soil if capable. They must be defeated.

MORE: Brigadier General Mark Kimmitt announced at a press conference the military's belief that insurgents were unaware of the shell's chemical payload, especially because the binary agents did not mix. Maybe. Overestimating one's enemies is safer than not — again, if they knew, they'd take full advantage. What if terrorists return to a source where there are many more like it? Indeed, further down the report, some experts weigh in on the implications, particularly in the WMD debate.

EVEN MORE: The IED detonated itself, but still without causing harm. And then there's this in an update of the same article to which I linked:

Two weeks ago, U.S. military units discovered mustard gas that was used as part of an IED. Tests conducted by the Iraqi Survey Group and others concluded the mustard gas was "stored improperly," which made the gas "ineffective."

They believe the mustard gas shell may have been one of 550 for which former Iraqi President Saddam Hussein failed to account when he made his weapons declaration shortly before Operation Iraqi Freedom began last year.

WMDs in Iraq? Fancy that.

IT'S OFFICIAL: For one news agency, anyway. The headline on Fox's website reads "U.S. Confirms WMDs Found in Iraq." And where there's smoke, there's fire. As I said earlier, is there likely to be a stockpile from where the sarin- and mustard-filled shells originated? There's more than enough evidence proving Saddam's gratuitous violation of Security Council Resolution 1441 (and every other resolution before it). But this could get interesting.
