But Japan's very imperialistic too. Not in the same sense as the United States because there's no way Japan would start a war. Yeah, but war is a thing of the past because it's not really economically viable. America just uses war as an excuse to use all the armaments that they build up. The United States have been run on what amounts to a wartime economy since the fifties which is the reason that Japan now has more economic power.
Japan is imperialistic economically, in the new sense.
When Britain and France were imperialist powers they were very up front about it because people were more overt about the idea of racial supremacy. Basically it's another change, like the rock'n'roll thing, a change that's based on economic necessity. It's cheaper to pay off a government than have an occupying army. Buy off the government or terrorise the government. In Central America the USA just coerce and bribe the governments.
