Funny how that didnīt apply to Iraq, yet look what happened there.
Not that Iīm advocating more war, far from it, but when a president says that he is going after someone "dead or alive", and then funnels billions to the people who protect said man...thatīs sad beyond belief.
And what is the lesson for Iran?
If you have no WMD, you get invaded.
If you have nukes, your sensibilities are respected and the US WILL play ball with you.
And people still think that Iran's nuke program is motivated out of a desire to wipe out Israel

A far more realistic, realpolitik reason is that they want to ensure their territorial integrity, in the same way that Pakistan has been able to.
