Si vis pacem para bellum, and there will be war. I honestly am unable to think of a scenario that will prevent a collapse of at least the US democracy, if not the rest of the world with it (because let's face it, the US picked up the tab to ensure the freedom of democracies while us Europeans stood aside). The only thing capable of stopping the spiral towards death is if the Democrats win a solid majority in November... but that is completely unrealistic.
