All the gestures that Palestinians do for "peace" can be taken away in a blink of an eye. They deploy troops and make a couple of arrests today; tomorrow they start shooting at schoolbuses.
All the gestures Israel is doing for peace are either permanent or very, very expensive to undo. Releasing prisoners, ceding land and control, agreeing to not defend herself - all of these things can (and, historically, have) resulted in less security and more death.
We are witnessing Oslo II, and I fail to see how the Israeli government has shown that it learned the lessons of Oslo I.
