For the same reason US troops today don't trust Afghans who are their "friends".
Put down the crack pipe for a moment . PLease explain to me why 60,000 Japanese-American kids and their parents needed to be put in camps .
You have to put yourself into the context of time and the American and Japanese cultures that existed at that time. Almost all the Japanese Americans at that time still had direct ties to relatives in Japan and were felt to be a potential threat. They could have simply jailed all the adults and older teens and placed the children in foster care. But there was a damn war to fight that was not of American choosing. You’re obviously very young and prone to believing revisionist history or stupid. Japan chose the fight we chose to win. Don’t bother making any further posts to me since you have not addressed any of my points and you have failed to make a point but I responded to each non-point as a course of being fair.
Oh I forgot, stick the crack pipe up your behind.
