I agree, no coup. On the other hand, if we the US keep changing alliances at the whim of what are essentially twitterheads, we could end up having ZERO allies.
Beau of the Fifth Column (Youtube channel for Justin King) would always emphasize (before he relinquished it all for his wife "Belle of the Ranch" to take over) that international relations are usually well-orchestrated, even between enemies, with speeches and releases using heavily coded language, to minimize the possibilities of conflict. Friends and enemies both would telegraph to some degree their intentions, their protestations, their agreements, and shifting policies ... very very carefully.
Trump, Vance, Musk ... have upended this all with their amateur hour antics. They are not serious people. They think they can rewrite the rules but they've bought us at least a decade of hurt and isolation on the international stage, and likely worse economic prospects for a while. Nobody will trust us, even if saner leadership comes round in a few years.
