>Which of those are active theaters of war?

All of them but Japan?

MEA has stuff going on beyond Iran, Lebanon or whatever country the US decides to invade this week. India has two nuclear neighbours with border disputes and weekly scuffles, sometimes a downed jet fighter or two. Taiwan is probably the biggest geopolitical tension/war/invasion possibility of our time. Korea is in a stalemate unfinished war for decades. Japan has its own very real dispute scenarios with China.

I know drone scans from Pokemon Go probably won't help in the Himalayas or South China Sea, but those regions are far from trouble free
