Debate it all you will, but FDR and the Gov't he headed stepped FAR over the line on that count at least.
And I'll throw in on the "Is it okay to round up Americans if they look like they might be trouble?" question. NEVER will it be okay to round up a bunch of citizens of this country based on what they look like or who they know.
Based on this hatred of Japanese-Americans because of what the Japanese military did means the rest of the world probably has plenty of reason to round up Americans in their nation just because of some of Bill Clinton's actions. Shoot, we hate the guy enough.
I lived in Japan for a time in the 1990s and I met several old men that were still sore about losing the war (like many Americans are even though they eventually "won" big), but I met far more old folks who were terrified of their own government at the time and were VERY relieved when Japan surrendered and their leaders were taken. Several of them told of how their entire family sat around the radio and wept with joy when Hirohito announced the surrender.
An old blind woman recalled taking all her younger brothers and sisters out in the fields and running for cover when the Allied planes would come on strafing runs through her farming village. Why were they a target? Was it just?
War is never good. The Japanese paid for the war their evil leaders put on them, just like the Germans did. Several on this thread seem to fall right in line with the mentality that allowed Hitler to take power over his people. Hitler's rise to power included the hold the "subversive non-loyal element" propaganda had on his countrymen.
But even though liberals and others are hacking at that foundation, I will never support the denial of rights to those who work within the processes guaranteed by the Constitution. It's my duty to work within that framework to uphold the foundation.
