No deterrence because the previous president didn't believe in deterrence or in supporting the military, and probably wasn't even on our side. The Russians are after the Baltic countries now, which are in NATO, and also NATO is supposed to maintain stability in Europe, not just directly within NATO boundaries. A few billions will make a lot of difference on readiness, ours has deteriorated tremendously and German readiness was shown to be laughable during maneuvers a couple of years ago. As far as spending more, it's a lot more expensive to maintain a military in US than in Russia, as a percentage of GDP I doubt that's true.
