Iran launches missles into Israel...... U.S. launches tactical nuke strike and turns Iran into a sheet of smooth glass.... and throws a couple North Korea's way too.  End of story.

The U.S. pops Israel off the proverbial American tit and the
U.S. Begins 100 year isolationism policy. Cuts all imports and turns to Nuclear and hydrogen fuel and watches the rest of the world tear itself apart because we are fully protected by our defense missle systems....farmers are no longer paid to NOT grow crops. We allow immigrants in because we have a worker shortage...welfare is for people who actually NEED it and Social Security becomes fully funded for 500 years. We explore space and invent hypedrive and leave this dusty rock for Eutopia on some distant world.

...... oh, nevermind, that was the dream I had last night.
