Well, Israel is bound by international law and is a (flawed) democracy. Doesn't excuse them from wrongdoing though, but it makes things more gray than black.

The rest of the nation's in the middle-east (or West Asia) are authoritarian nations that brutalize the population on occasion. Jordan in black September springs to mind as the Palestinians tried to overthrow the Jordanian rule and conquer it.

So, yeah, it is complicated.
