You do it like the Israelies did to Iraq the 1970's(?). You blow up a strategic piece of their nuclear reactor progran before it left, in his case, France. And then, 3 years or so later, when the repaired reactor core was installed.....you bomb it so that it will never become operational.
Hopefully, similar thinking is going on in Washington. If not, I am confident that it is going on in Tel Aviv. We are geting down to short strokes on this one!!
Oh, sorry. We should allow our representatives to throw it over the fence and say "war powers act". Then the executive is damned if they do (Iraq) and damned if they do not (Saudi Arabia). I disagree. It should be a public vote on the floor of the House and Senate.
