One shouldn't lump all antagonism towards a government together as a single thing.
You can live in China, think the US government has a history of war crimes, subjugation, imperialism, plunder, genocide, and geopolitical treachery, and yet not want to go to war with the US.
You can live in the US, think the Chinese government is engaging in genocide and creating an uniquely dystopian surveillance state where all thought and behavior can be monitored and shaped, and yet not want to go to war with China.
I'm sure this trap is a real phenomenon, but pretty much every large human empire has been powered by a helm regularly committing horrible atrocities, so one hegemon will probably always be able to legitimately condemn a up-and-comer, and vice versa.
I think it can be a bit dangerous to counter such discussion with accusations of war-seeking, because it lets rulers get away with more than they should. At least unless you have specific evidence suggesting the discussion isn't simply a case of people who are genuinely concerned about people for humanist reasons.
