Excuse me? Rogue governments?
When you have 20% of humanity to provide for you can't just ignore huge masses of land, some of the largest food producers(USA and Brasil), for any reason whatsoever. Especially Brazil, China buys millions and millions of tons of food from us every year, do you propose both them and us to starve and get fucked just because our current president is shit? Do you support unilateral sanctions? Because that's what they do.
We're seeing it with Russia - you can't just ignore a continent-size country. Regardless of regardless.
Never, not even about taiwan, did I hear everyone spamming so much the word "sovereignty" as if it was something most countries actually have.
Really, there's probably like 10 countries that are actually sovereign. If that.
