Shock! Horror! President Trump is actually doing something right.

Sadly, Democrats in Congress are responding in a quite Trumpian way: They seem more concerned with undermining him than supporting a peace process with North Korea. They are on the same side as National Security Adviser John Bolton, quietly subverting attempts to pursue peace.

While international security is complicated, here’s a rule of thumb: When you find yourself on the same side as Bolton, go back and re-examine your position.

Sure, we all wish that Trump treated Justin Trudeau or Angela Merkel with the respect that he now shows Kim Jong-un. Yes, it seems that Trump has been played by Kim. Yet another way of putting it is that Trump is finally investing in the kind of diplomatic engagement that he used to denounce, and that we should all applaud.

Trump’s newfound pragmatism is infinitely preferable to the threat of nuclear war that used to hang over all of us, so it’s mystifying to see Democrats carping about any possible North Korea deal.
