In fairness, you have to give Abbas the benefit of the doubt about how the Palestinians are going to free Shalit. After all, the Palestinians would never promise something to Israel and then fail to follow through on it:

Now why would diplomatic officials express skepticism over Abbas's promises? Maybe because he has no power and Hamas says they're not going to free Shalit. But that's just a guess:

Yet again, we fail to see why we should care whether Abbas is a terrorist, working for terrorist,s or unable to stop terrorists. The result is the same: crimes against Israeli soldiers and civilians by Palestinian terrorists and militia.
