I suspect that massive destabilization following the precipitous fall of most of the great powers (NATO + Russia at the least) would result in war on every continent (sans Antarctica). If Asian countries don’t get nuked in this scenario like you suppose, I think it’s quite plausible general war in Asia would follow shortly as the surviving greatest powers jockey for dominance. If we posit the complete collapse of U.S. power projection in the Pacific, surely China is best positioned to fill the void, and I don’t think it’s clear where they’d draw the new lines.
