Said the guy who prolonged the depression and sent Japanese Americans to internment camps.
Says the guy who any credible historian will agree brought the entire country out of the worst depression we have ever had. Sure you are not confusing him with Hoover? It's called the New Deal. Look it up.
Also, what you are doing is called "perverse presentism". Looking back now, we can see how wrong japanese internment was. But you have to remember, these were people living in a time when the entire world was at war. Pearl harbor had just happened. It was their version of September 11th... the worst attack on the United States in history. Countless millions around the world were dead, and a blood thirsty killer (Hitler, the Italians, and their allies the Japanese) were hell bent on landing on US soil and killing as many of us as possible. (and FYI, nazi's did land on US soil)
So yes, people overreacted and moved Japanese americans out of the west coast because there was a very real possibility of a Japanese invasion and there wasn't time to find out who was an enemy and who was a friend. Was it wrong? Yes. But these were people living through a world war that impacted the lives of damn near everyone on the planet. These were people who just had American civilians and soldiers killed on US soil in an attack that makes September 11th look like a day at the park. They didn't send Japanese americans to internment camps because they hated Japanese americans. They did it because the whole damn world was going crazy and at the time it seemed like a necessary evil to prevent the United States from being conquered.
It's easy to sit here in the present, having full knowledge of the situation, and pass judgement. Chances are, if you had been alive at the time, living through that war, and knowing only what limited information people knew back then, you would have been 100% on board with japanese internment just like damn near everyone else was.
Go pass judgement on American's living through possibly the worst time in US and world history from your comfortable life of peace and processed goods being delivered to your door step. Let me know when you live through a world war and manage to not overreact and make zero mistakes when dealing with every situation.
FYI - people are taught about Japanese interment in school so that we don't make the same mistake again. (i.e. like locking up all Muslim's after 9/11 like some people wanted to do) You are taking this teaching and saying "Oh everyone was a racist anti-japanese thug!" back then. That isn't the point at all. We in the present can see that it was wrong because it was racist and unnecessary.... and the point is that we should never do it again for that reason.... not that the people at the time who created and supported the policy were evil, because they weren't. They were just scared because it was a terrible time for the United States and the whole world. Fear can make people do crazy things. Japanese interment wasn't motivated by hate as you want people to think, it was motivated by fear. And the lesson is not to let fear make policy.
If you want to see interment motivated by hate rather than fear, then go look up Nazi camps. Those are camps constructed using hate as motivation. US Japanese interment camps were constructed using fear as a motivation. Nazi camps were designed to kill, American camps were designed to relocate until the crises was over and they could figure out WTF was going on.
