Now let's say China stops supporting NK.
NK is screwed. It'll starve, and perish.
Tbh I think the countries that MIGHT start the war are, Pakistan, China, NK, Russia. Pakistan because historically, they've always went to war with India and in 1971, it got huge. Like America and Britain were about to siege India but the USSR intervened on India's behalf. Then it got small again. China is a country that wants to take over the world, no doubt they are hostile. I don't have to explain NK. Russia invaded Crimea and Georgia. Plus they're under harsh sanctions and the inflaction there might make them start a war.
