My dad had some scarry tales of mob violence in Houston,Tx in reaction to Pearl Harbor-thus he was of the opinion the removals were also intended to protect the Japanese-Americans. Have no idea if he was correct.
The forcible confiscation of homes, businesses, land, and family members on the basis of race is NOT justifiable under ANY circumstances. This much is clear from our President's laudable commentary in the wake of the 9-11 attacks.
Removal of Japanese-Americans was couched by the liberals in FDR's cabinet as being for "security" and "protection of the individual". However, the real truth is apparent when one does a thorough analysis of the land, business, and asset conversion following 1942. Look at who and what gained the lands on Bainbridge Island, Washington and Terminal Island, California.
You should evaluate the real economic reasons that Americans of Japanese descent were put in a concentration camp by FDR. The reasons are political and economic. Someone wanted to alter votes. Greedy others wanted the land and businesses (because they were too weak and too corrupt to actually build it themselves).
