China quite possibly. The first country the CCP conquered was arguably China itself, ditto for the Soviets and Russia. Pakistan and India over Kashmir, that's an historic dispute. I would suggest that both of you leave things as they are, at least until you prove there's anything there that's actually worth fighting over.
Ah yes, the old, "I'm a free thinker," BS. Some great minds of the past have gone against popular opinion and heralded breakthrough, Einstein, Galileo, Newton etc. but usually it just means you're an idiot. Russia has been preparing for this war for a long time. Ukraine was infested with FSB top to bottom. They had even moved ammo into the country beforehand, it was in the planning for over a decade, combined with provocation elsewhere in Europe too and a build up of new arms.
