Charles Krauthammer: "The real news from Wales is what NATO did not do. It did not create the only serious deterrent to Russia: permanent bases in the Baltics and eastern Poland that would act as a tripwire. Tripwires produce automaticity. A Russian leader would know that any invading force would immediately encounter NATO troops, guaranteeing war with the West. Which is how we kept the peace in Europe through a half-century of Cold War. ... That's what deterrence means. And what any rapid reaction force cannot provide. In Wales, it will nonetheless be proclaimed a triumph. In Estonia, in Poland, as today in Ukraine, it will be seen for what it is -- a loud declaration of reluctance by an alliance led by a man who is the very embodiment of ambivalence."
