The USA is historically inclined to isolationism because of geography. The voters are now inclined to isolationism and the end of 'the brotherhood of nations' because of social media access, authoritarian agitprop, and failure of the American elites to keep the domestic situation comfortable and understandable. It will take a while before these trends reverse.
There is no point relying on an extractive, transactional, reluctant protector. The democracies of the world will have to arrange to engage in collective deterrence without the USA, because nothing is worse than having the rug pulled from under you at a critical time.
