Quick, someone put up some “Nuke Free Zone” signs. That will solve everything.
I am sure the Japanese have the ability to ramp up a nuke program rather quickly if they so chose to do so. Frankly, they could just lob pieces of Fukushima at them.
Interesting the NORKS are picking on Japan as the aggressor state here. Their obvious intention is to take over the south. I guess if Ho Chi Minh had had nukes, he would have threatened Tailand while working to take out the south too. Same principle, point one way while moving another.
