Palestinian PM Mahmoud Abbas has a problem. He rules over a culture of psychopaths. Not more than a metaphorical ten minutes after the Israelis yanked their citizens out of Gaza, one of his is once again behaving like a certifiable homicidal maniac. Does Abbas have the guts or even the conviction to do anything about this? He hasn’t shown it so far. Not even close. If I were the Israelis, I’d keep building that wall. I assume they are.
