They are run by a military dictator who got his job by staging a coup.

They have many working nukes and the missiles to carry them.

The populace is heavily Muslim and certainly not fond of US.

Not ignoring Iran, but how do we intend to seriously stop them? Whether
you consider Iraq to be a failure or not, we do not have the resources to
do much about Iran, which is much bigger and stronger than Iraq at its
peak.

Except nuke them. Is there such a thing as a strategic nuke attack?

And don't bother bringing up Hiroshima and Nagasaki. No one else had
the Bomb then.

If we had left Iraq alone, even if they did develop WMDs, how much
danger would we really have been in? Getting rid of Saddam and his
cronies didn't make the place any better or safer.
