You could be right.
Personaly I'd like to see Abbas "do something" about terrorism in the PA. But He can't, and I suspect he doesn't really want to. The problem with the PA is by this stage of the game anyone who wants too make peace with Israel is at room temp., and has been for a while now.
As my students would say, "True 'dat!"
The problem has always been that Israel is expected to behave towards terrorists the way that we would treat honest partners. That's not a problem with the Palis... it's a problem with Israel's allies...
