They're not old enough to remember the start of the war in Iraq, I imagine. For those who aren't: it was a barrage of justifications which were found to be untrue, especially the 45 minute claim which said Iraq could strike European targets within 45 minutes with chemical or biological weapons. The UN weapons inspector said this was nonsense, and so it proved to be - after the invasion.

Iran will go the same way, one way or another.
