Hillary Clinton’s foreign-policy speech last Thursday showed what a nightmare Donald Trump is for foreign-policy realists, like me. Sure, Trump makes regular statements about allies, autocrats and war that seem consistent with my kind of realism: a more peaceful and less ambitious U.S. foreign policy. But he combines those thoughts with various bad and terrible ones—on trade, immigrants, torture, ISIS and more— and markets the package with the gravity and honesty of a dude on a corner trying to sell you the Rolex he has in his coat.



Trump’s endorsement may taint the realist notions he’s been poorly articulating on the trail, especially once he loses, as is likely. He offers defenders of our current meddlesomebellicose and counterproductive strategy a perfect foil. He allows them to conflate prudent military restraint with protectionism, nativism and incoherence, label it all isolationist demagoguery, and then exhort everyone, in the name of decency, to toss the baby out with the bathwater.
That’s partly what Clinton is doing in the speech by casting the election as “a choice between a fearful America that is less secure and less engaged with the world, and a strong America that leads to keep us safe and our economy going.” Setting up that choice may be good electoral politics, but it’s bad for U.S. foreign policy, or at least for sensible discussion of it. We could easily be less aggressively engaged in the world and safer and richer for it, without closing down borders or withdrawing economically.
