MORE STATEMENTS OF THE OBVIOUS: From today's Jerusalem Post editorial:

The urgent task is not to define the political horizon but the opposite: All talk of horizons, all conference preparations, all envoy missions, all time line preparations should simply stop. Because if they do not stop, the message is that the more Israelis are murdered, the more the world will run around looking for something to give the Palestinians so that they will stop.
The lesson of the failure of the 2000 Camp David summit and the subsequent Palestinian terror offensive is that peace cannot be achieved by satisfying Palestinian grievances. Camp David was the ultimate experiment in providing a political horizon. It failed. It failed because there is no fixed set of Palestinian demands short of Israel's destruction.
This does not mean there can never be peace with the Palestinians. Egypt and Jordan also had unlimited grievances, and potentially still do, but they made peace for lack of better alternative. In the pivotal case of Egypt, peace came not, as many argue, because Egypt was able to restore its honor from the trouncing it received in 1967, but because the 1973 war was once again a massive military defeat.
In other words, the real "political horizon" is the elimination of an alternative to making peace. This is what the current war with the Palestinians is about, and the sooner we win it, the sooner the clouds blocking the political horizon will disappear.
