We know deterrence was never restored because Iran was willing to try the same trick again in Baghdad this week.
In killing him Trump reestablishes the deterrent threat protecting US embassies that was lost in 1979.
This is a message directed not just to Iran, but at China and Russia too.
But keep your eye on the ball: A free nation has to be able to deter attacks by its enemies.
What Trump did today was to rectify a weakness in the US deterrent posture that has dragged on for 40 years.
This was the right thing to do. Americans should feel proud that their government wasn’t afraid to do it.
You can’t maintain the existence of a free nation for free.
