Donald Trump is threatening Japan.

Mr Trump threatened Japan that, under his presidency, it could be necessary to "walk" away from the treaty. "It could be that Japan will have to defend itself against North Korea," he said. "You always have to be prepared to walk," Mr Trump said about getting allies to carry their financial weight. "I don't think we'll walk, I don't think it's going to be necessary. It could be, though." (The Telegraph)

Donald Trump is threatening Japan. He demands that Japan should pay more. In principle, America should, at its own risk,  withdraw their military in Japan and return the land that the US bases are occupying  to Japan. We don't welcome proxy wars on our land.
