Maybe you should at least read up on the history of Okinawa's occupation before writing the effect of America's presence there off as "boisterous 20 year old Americans." How would Americans feel if China invaded California, slaughtering hundreds of thousands of civilians in the process of occupying the land by force, completely destroying the local culture and economy, raping and killing more or less without consequence, and then never left?
You can argue (probably correctly) that the US presence in Japan has done a lot of good and that it's necessary for Asian stability, but I wouldn't write off any anger or hostility that might be there as NIMBYism. They have legitimate complaints about the way the US has conducted themselves.
Your analogy is incomplete because you left out the part where this fictional America conquered all of its neighbors and engaged in mass rape and murder and was in the process of attempting global domination in tandem with the Nazis. And if you're referring to the nuclear bombings, then perhaps you aren't aware that the US had encountered nothing but total violent resistance from Japanese populations that they had occupied. An invasion of the mainland would have been an absolute blood bath, and Japan refused to surrender.

I removed the sentence from my edit because it's just served to distract from the content. And it's just as likely, or more likely, to be a bunch of self-motivated idiots.
I do agree that it is sometimes frustrating that people downvote without commenting and offering any other views (which, if void of positive contribution, would expose them themselves to downvotes).
Is the US claiming vast swaths of other country's territorial waters and building military bases on artificial islands? No, that's China. The US defends the countries that China is trying to bully that way.
South Korea, Taiwan, Japan, America. Seems like a righteous alliance of free people defending themselves against evil from China and North Korea. The evil of a boot stomping on a human face for eternity.
Edit: Any arguments from the downvoters?
