Being french this argument annoys me particularly because if you remember France was against this intervention because we thought the WMD menace was bullshit. Turns out that we were right. Then a few years ago France was saying "Assad is using chemical weapons against civilians, we must do something!" and the whole internet started parroting the russian talking points "But remember Iraq!!! It's all a bunch of lies!!!".
Not to say that french intelligence is infallible or can't be manipulated but using the garbage fire that was the "Gulf War Episode 2: The Empire Strikes Back" to immediately dismiss any kind of foreign intervention is rather disingenuous. Yet an other terrible long term consequence of the Bush administration years I suppose.
A public reticence to create further disasters, if indeed it existed, would be among the best possible long-term consequences of that foolish administration.
