If the bigoted racist US government of the day decided to send Japanese citizens to concentrations camps then that might hold some sort of reasoning when debating the issue but what is morally indefensible is when you have a government sending its own citizens to concentrations camps because
they might help the enemy during the war.
That's a quite interesting point of view. Another country does in Pearl Harbor, kills thousands of US Citizens, declares war n the US, and is universally understood to be the enemy, but citizens of that country are not the enemy. Since a country is comprised of citizens, I think a lot of people might have a problem with that.
Regardless of that, the link I provided provides the actual thinking and reasoning for these historical realities. So there is no need to shroud the desire to generate virtual signaling based on false pseudo-history. None whatsoever.
