Also, North Korea is under the protection of China. Partly because they&#x27;re allies (sorta), and partly because China just doesn&#x27;t want people messing around near it. One might recall the <i>last</i> time we tried to take over North Korea. Once we got close enough to the Chinese border to make them uncomfortable, a million or so Chinese troops poured over and made life somewhat difficult for the US and their allies.<p>And that was 1950s China, fresh out of a massive civil war and struggling to get by. 2016 China is far more powerful.<p>If you want to complain about how nobody does anything about North Korea, look at who&#x27;s protecting them to see why that is.
