Actor and activist George Takei slammed Donald Trump on Tuesday for his Islamophobic proposal to ban Muslims from entering the U.S., suggesting that the real estate mogul hasn't learned the tough lessons from the incarceration of Japanese-Americans during World War II.

Trump has campaigned on a promise to "Make America Great Again." Takei, whose family was forced into a prison camp when he was just 5 years old, said Tuesday on MSNBC that the slogan should be more like "America Disgraced Again."

Trump's widely criticized proposal has drawn comparisons to the United States' disastrous, xenophobic decision to place some 120,000 Japanese-Americans into camps during the war -- a policy Trump would not outright disavow.

Takei noted the irony that Trump issued his anti-Muslim proposal on Dec. 7, which is Pearl Harbor Day -- "the very event that put us in those internment camps," the actor said.
