since america is an island that gives a damn about the rest of the world and only seeks to take advantage of the rest of the world, the rest of the world shouldn't really care.
Roughly one quarter of Americans are first or second generation immigrants. Are you saying that this group of individuals are not concerned about the rest of the world? And there are MANY third generation Americans (Irish, Italian, Russian, Chinese, Korean, etc... who also give a damn about the rest of the world.
Americans do care about the rest of the world - or more particularly - parts of the rest of the world. Does the average Russian or Chinese or Indian citizen really give a damn about what happens in Suriname or Ghana or Canada? I would guess the wouldn't care anymore than the average American (unless they came from Suriname or Ghana or a neighboring country).
