President Trump abandoned a nuclear non-proliferation deal in which Iran is thoroughly inspected and shown to have demonstrated compliance. Experts (including his own advisers, since fired) advised him to stay in it. Now what?

Perhaps a little history will tell us. In the 1990s, President Clinton made a non-proliferation deal with North Korea, which pretty much worked, if not perfectly. George W. Bush abandoned it, then North Korea started exploding nuclear bombs.

Russia and China, looking to sideline the West in their campaigns for greater influence, cheer as Trump marginalizes the U.S. with this withdrawal, his threats to NATO, his adoration of strongman rule around the world and the open corruption and incompetence of his administration.
