Basically the reason why Vietnam won because the Vietnamese wanted to win more than the Americans did. There were a couple of reasons for this. First, the Americans were an invading force, and the Vietnamese were fighting on their own soil. Second, the Americans were not willing to make an all-out commitment to win.
When a government acts against their common interests and/or threatens the safety of the people without cause.
I'm not sure but I'd say because of Japan, Japan more or less did not get involved in many wars as far as I know. I know that Japan had no reason to go against Korea but still did and sided with China/North Korea. Because of that a lot of hate came from that and since then even sometimes now South Koreans are not very fond of Japanese.
Also I hope no one takes offense that's what I know I'm not saying all Koreans hate Japanese just some...
Hope this helps
