Line was crossed already lol.
If China is not already sending covert help to Russia, I'm betting it soon will. And there's not a goddamned thing we can do about it. China alone doesn't fear the US. Or the EU. If China aligns itself with Russia in an actual military pact, that reduces the US to impotence. Together they can do anything they want, forge ahead with their individual agendas as long as they don't step on each other's toes.
I'm betting that happens, too, eventually.
