Well lets be frank here. Yes, other governments are worse then our own (US) government. Yes, the governments dealings generally negatively effect much less of the US population then most really realize. That all said, the United States of America is supposed to be the best, most fair, most democratic and most self governed (by the people.) This just isn't the case anymore, what with the massive amount of people we have compared to what we had when the founding fathers first drafted our governing systems, the ridiculously up and down economic situations we seem to get ourselves into (by the way this ones just as much the people's fault as the governments. If you don't believe me start spending your money better and you soon realize life isn't that hard on a low income.) and our biggest fault of all, arrogance in thinking we have it right and trying to enforce our democratic ways(that obviously aren't working.) on other people, wasting valuable money and resources we could be using for say, better education, better public transport or maybe even leveraging technology to alleviate common problems. (that's an entirely different subject I won't get into.)

In Summary, we (the American government and people to an extent) think we are better, our hubris is our downfall and we use the excuse of we aren't as bad as A to justify an act of B. Sure North Korea's government is straight up tyrannical, but we aren't the best, if we were this wouldn't be happening.
