“institutions like the UN, IMF, World Bank, NATO and the like that keep the world from blowing apart”
Every one of those spreads misery, war, loots America, and destroys freedom. Each of those mostly provides full employment for legions of EU bureaucrats. Sad that anyone still sees those as making a better world.
Granted, all of those institutions are flawed -- in some respects deeply so -- but they are ultimately supported by the US for strategic reasons, not emotional or romantic ones. Thus the Reagan administration kept them, reformed them to a degree, and used them -- successfully -- against the Soviet Union. The same can and should be be done to curb both Islamic radicalism and Chinese expansionism. I trust that you would support those objectives at least.
