My two cents worth (or maybe less if I turn out to be wrong)

Maduro's capture sets the stage for Russia to do the same with Zelenskyy, it would remove the primary stumbling block to ending that war and remove an embarrassment for us, so public posturing aside we probably wouldn't complain much and might even quietly help.

Question is will China use it to take over Taiwan? If I were in the govt. of Taiwan I would not be sleeping easy right now.

Three pole political order shaping up. Russia controls Europe, US controls western hemisphere. Asia goes to China, possibly as one of two or three (Japan, Philippines)

Europe has far more in common with Russia now than it does with us, remember they were playing footsie with Russia pre-Nordstream, we exit NATO (likely in my opinion) and the EU crumbles. With their failing economies and proto-Communist leanings they will probably become an anchor around Russia's neck for some time.

With the oil reserves of South and Central America in our sphere of influence the Middle East and all it's issues (strategic choke point of the Straits of Hormuz, Islamism, etc) becomes an also ran, if they can't get their act together they will end up divided between Russia and the Asian bloc. It would be unwise for us to get involved in Iran, remember it wasn't that long ago they were yelling "Death to America". Death seems to be a popular and historical theme in the Middle East, old Persia specifically.

Which leaves Africa, unclear where interests lie there. It will most likely end up as the next area of contention, nee Middle East.

Antarctica also has the potential to become a contention point, though further out.

Circling back to Maduro, this makes a major change to the old rule that once you attained power as the head of a govt, and weathered the inevitable challenges, you were safe because even if you were forced out you would quietly live out the rest of your days in a villa in some other country. Now there is a new end point.
