U.S. General Wesley Clark thinks that America should resort to the archaic tactic of putting “lone-wolf” terrorists into internment camps, similar to what Japanese-Americans endured during World War II, reported Talking Points Memo.

“In World War II, if someone supported Nazi Germany at the expense of the United States, we didn’t say that was freedom of speech, we put them in a camp, they were prisoners of war,” said Clark. “If these people are radicalized and they don’t support the United States and they are disloyal to the United States as a matter of principle, fine. It’s their right and it’s our right and obligation to segregate them from the normal community for the duration of the conflict.”

Clark’s comments actually surprised some. Murtaza Hussain of The Intercept said Clark, who’s a former Democratic presidential candidate, once called the American response to 9/11 a “Bush-led imperialist strategy for the Middle East.” Despite that, Clark said that if “people choose ISIS, they should be treated as spies or enemy combatants.”

The problem with Clark’s idea is that hundreds of thousands of Japanese-Americans were placed in internment camps with no connection to the Japanese Empire. It was racial profiling, which is the same thing that would happen under Clark’s suggestion for Muslims.
