Lots of places have been peaceful through the reign of some strong man dictator. Cuba has had peace for a long time. The people's standard of living ain't that great though.

The third reich brought peace to millions, but millions more were deemed undesirables.

All a matter of point of view. Dividing the world into a dualistic view of good/bad or right/wrong, us/them, is very dangerous. Look how fabulously it has worked so far...

Even if funds and parts are unlimited (and the never are) maintenance requires someone to get dirty. Sometimes very dirty.
