As many of us have mentioned before, Putin must have some decent kompromat on the orange thing, failing that Trump does not care about any sort of world order and sees Russia as a significantly better chance for him and his cronies to make more money as opposed to the significant financial liability that is spending more money backing Ukraine. Which of course is true.
It's so crass, it's Trump, and in the long-term the US are going to lose a significant amount of soft capital world-wide when from election cycle to election cycle they are willing to flip-flop so massively on the world stage. Isolationism will only work in the very short-term. The rust-belt will surely learn quickly that their standard of living is diminishing with tariffs and inflation. The manufacturing jobs they expect to return are never coming back, they are simply not viable, and they have been fed a massive lie.
