I have no problem with Japan having a military....
But they better know: next time it will be the whole island, not just 2 cities.
Germany too, for that matter.
Japan isn’t thinking about US with these carriers, they are a message to Chinese Emperor Xi. Obama scared Japan into rearming. For 60 yrs. the Japanese knew we had their back and Obama’s dithering in the Pacific and around the world shocked them as well as many of our allies, Australia being one of them as well.
Depending on the Norks behavior Japan will go nuclear sooner or later as a deterrent to the new Greater East Asia Co-Prosperity Sphere being aggressively ran out of Peking.
