It would mean taking a stand against the Oslo proselytist crusade against Israel. Jews were taught that only G_d can proselytise, which is fine, but some fear that taking a stand would mean Jews would start proselytising the world. But this is the same stupid logic that Jews applied in Nazi Germany, when Germans accused them of proselytising Germans because a few Jews were present in the press.
This means that leftist Jews are considered proselytiser by Palestinians and are probably hated more than the right wing Jews who have a lower profile. This means that Jews have a problem getting to agree with each other, proselytising to each other what the word of G_d was, and this means that Jews/Israelies, from the left and the right, are still very uncomfortable with the struggle to prevent the destruction of Israel by foreign proselytism, believe it or not.
IMO, if the government of Israel suddenly gives up Oslo, the Palis, with their friends still living in their homelands (i.e.: Egypt, Jordan, Iraq, Syria) and their enablers throughout EUroweenie land, will unilaterally condemn Israel for "not truely wanting peace". It might even give some Arab country an excuse to invade Israel again.
