> And what does U.S. has anything to do with any of this stuff, anyway
This is whataboutism and has far less relevance in foreign affairs than in interpersonal ones.
The U.S. Government has incentives to keeping the South China Sea's international boundaries in line with the U.N. treaties. Much of, if not most, of the world's trade passes through there. Since the U.S. economy depends on this trade, it is considered to be one of the most important things to protect.
The U.S., just like every country, is primarily self-interested. It makes sense for the U.S. to want to contain what it perceives as aggressive moves to claim what have previously been considered international waters.
In the spirit of fairness, the Russian Federation considers NATO enrollments of neighboring countries to be aggressive behavior on the part of the U.S. The U.S. isn't the only country threatened by apparently threatening behavior.
The U.S. would defend its involvement in Syria, Iraq, Afghanistan, and in Pacific Rim countries in terms of its self-interest for stability in those reasons, stability being a euphemism for unrestricted trade.

I'm not familiar with U.S. involvement in Ukraine; it's not a NATO member and the U.S. hasn't (publicly) committed forces there.
