Republican presidential nominee Donald Trump again ripped into ally Japan on Friday, saying that if the U.S. is attacked, Washington must defend the country but the Japanese “can sit home and watch Sony television.”

Speaking at a rally in Des Moines, Iowa, Trump blasted as unfair U.S. defense tie-ups with NATO, South Korea and Japan, a reprise of comments that have earned him scorn among many in the national security community.

“You know we have a treaty with Japan where if Japan is attacked, we have to use the full force and might of the United States,” Trump said. “If we’re attacked, Japan doesn’t have to do anything. They can sit home and watch Sony television, OK?”
