>3% of the population was killed. 8% of Germany died during WW2, and they suffered under enormous foreign debt afterwards. Two million Vietnamese died during the Vietnam war. 4% of Japan died during WW2, and they also happened to have nuclear weapons used against them. The Korean war was enormously destructive, and after the cease fire, most of South Korea's industrial base ended up on the wrong side of the border. South Korea operated under a military dictatorship for decades. Vietnam is still a single-party Communist state, with attendant corruption and looting. All four countries are dramatically richer today than Haiti. Disasters and foreign debt don't explain the difference.
