I was born into the Israeli left. I grew up in the left. I was always a member of the left. I believed that the day that the Palestinians would have their own sovereign state would be the day when Israel would finally live in peace. But like many Israelis of the left, I lost this certainty I once had.

Why? Over the last 14 years, I have witnessed the inability of the Palestinians to utter the word "yes" when presented with repeated opportunities to attain sovereignty and statehood; I have lived through the bloody massacres by means of suicide bombings in cities within pre-1967 Israel following the Oslo Accords and then again after the failed Camp David negotiations in 2000; and I have experienced firsthand the increasing venom of anti-Israel rhetoric that only, very thinly, masks a deep and visceral hatred for the state and its people that cannot be explained by mere criticism for the policies of some of its elected governments.

But one of the most pronounced moments over the past several years that has made me very skeptical toward the left were a series of meetings I had with young, moderate Palestinian leaders to which I was invited by virtue of being a member of Israel's Labor Party.

I had much in common with these young Palestinian leaders. We could relate to each other. However, through discussion, I soon discovered that the moderation of the young Palestinian leaders was in their acknowledgement that Israel is already a reality and therefore is not likely to disappear. I even heard phrases such as, "You were born here and you are already here, so we will not send you away." (Thank you very much, I thought). But, what shocked and changed my approach to peace was that when we discussed the deep sources of the conflict between us, I was told, "Judaism is not a nationality, it's only a religion and religions don't have the right to self-determination." The historic connection between the Jewish people and the land of Israel was also described as made-up or nonexistent.
