Being nice to Russia because the US are so evil to them? Let's be frank here, Russia's no saint either.
Evil loves evil.
Good relations with Russia? Not bad, but if you're pissing off 18 other G20 nations, it's not a great deal (as would say trump), don't you think?
It's in great deed to American orders, why the other G20 countries don't like Russia. And even then, most the weighty ones like China, and India, they are neutral.
Pissing off the G20 nations is a joke. West Europe, Canada, Australia, Japan, etc are all our pets. They just whine every once in a while.
Well, most the small ones (like the ones you said) are, but China, India, Brazil, Japan, Russia, these are not American "pets". Japanese and American interets usually just overlap. Be scared of China? Yes. Hate Choson? Yes. Hate Russia? Yes.
