Your leaders, sir, have been put there by voters. One of those voters may even have been you. So don't put the blame on them. In democratic and pseudo-democratic countries, leaders are just reflections of their populaces.
Oh, and just to make sure you don't think this comes from some partisan BS, the other side would have done precisely the same thing.
Now go and get yourself a serious government.
The US fight in the Pacific probably saved many lives elsewhere in Asia, the surrounding archipelagos, and Australia. We were allied with just about every other country fighting Japan.
If everyone had just surrendered to the Japanese, there would have been much fewer deaths in the Pacific theater in WWII. The point of fighting that war was not about saving the quantity of lives, but the quality of them.
