Was the U.S. justified in our treatment of Japanese Americans during WWII?

It was justified, at the time that is. Now it can be considered as a embarrassment on the U.S behalf by some because it hugely violated civil rights, the constitution, and we came to find out not many Japanese interned were actually spies. However people at the time feared how loyal the japanese were to their country, i mean they were resorting to kamikaze missions, plus the racist propaganda against helped justify it to a majority of the people . Like Reagan said it was based off prejudice and war hysteria. It was effective in protecting us from infiltrations,etc,etc but most can agree is was a little extreme

Yes, As a young man, I heard the stories of people who lived near Japanese communities in Southern California at the time. There were actually celebrations following the reports of the attacks at Pearl Harbor. Many Japanese felt that Japan was going to become the ruler and their status greatly elevated. For everyone's safety, it was necessary to inter them. Not all Japanese were treated fairly by this, but it did guarantee the safety of them and their families. The country was protected from Japanese sympathizers.

We didn't round up first or second generation Germans or Italians and ship them to camps. Mostly because they were very numerous and they tended to look just like most of the rest of the country. While we couldn't "trust" Japanese civilians to live in their communities, we didn't have any trouble trusting a great many of their sons who enlisted in the military and thereby had regular access to modern weapons.

While the security concerns were real though largely overblown, they were treated differently than other groups.

In short, no. Detaining citizens against their will for no crimes committed is in violation of the Constitution. Legally, however, there was no violation. United States or federal citizens aren't privy to Constitutional rights. Those rights belong to State citizens (The We the People of the Constitution). Federal citizens are given their civil rights by the federal government, which means the federal government can take them away. It depends if you want to view it as a legal or moral issue.

The war department was overly concerned that people of Japanese heritage would spy on the couuntry and send sensitive messages back to Japan. Do I think it was fair or warranted ,no. How ever we were at war with both Germany and Japan and I think they were trying to cover all their bases. Every country has it's own skeletons and this unfortunately is one of them.

it was justified at the time because people were actually scared for their lives. anti-japanese propaganda flooded america and every japanese was the enemy. but as we look back we see that it was just the ignorance of people. we have learned alot since then. or i,d like to think so.

NO. It was based on the same paranoia and phobia that is inciting people to hatred of Muslims and Middle-Easterners now.

Yes, we did what was needed. What if they sent sleeper cells over to attack us? They easily could have, after Pearl Harbor we had to expect anything!

The US did what was necessary to ensure the safety of the country and its citizens.
