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.
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.
