Locking up people based on surname certainly puts FDR in the lower end of civil liberties, does it not? US support for various chinese forces during the war is also pretty scary when you srat looking at what we got for our effort/money—they did not fight the japs, they fought other chinese, to the tune of some pretty large-scale democide (the various US service branches had their own intel ops in addition to the new OSS, in central China it was actually of all things the USN that was involved. Got pretty sketchy, actually, with the USN funding nationalist chinese secret service forces that mostly murdered internal political enemies.
That's aside from using the FBI to spy on political enemies, etc (standard practice, Truman did the same). Some of us might argue that starting social security was a major attack on liberty as well.
