People hate the U.S. because they fear the U.S.--with some justification. No other nation has meddled in so many other counties. The U.S. government see it as it's duty to govern the world.
Perhaps we ought to take a cue from Costa Rica and get rid of the military. Our government hasn't shown that it can handle such power in a responsible manner. We can contract defense out to Canada or Mexico, or some other country.
Uh, I don't think that part about no other nation meddling as much as the US is true.
For one, European nations colonized the US, booting out pretty much all the natives. This includes England, Spain, and France. Additionally, a few European countries basically carved up the entire continent of Africa among themselves and turned them into colonies. To this day Africa is engulfed in territorial battles over lines drawn on a map that don't mesh up with tribal and cultural boundaries.
I dunno, I guess it has to do with how you look at it. The US is in a huge number of countries, mostly doing nothing. The shear volume of nations we're involved in is probably higher than any other nation. I would still contend though, that in the global scheme of things, there are European nations who've meddled with greater impact than the US. I mean, they colonized an entire hemisphere and carved up an entire continent. That's pretty big meddling.
