Some Israelis and friends of the Jewish state can’t understand it. They see this willingness to help even enemies as a particular form of weakness.
Others think that it was wrong of the government of Prime Minister Benjamin Netanyahu not to exact concessions from the Palestinians in exchange for what may well be the best chance of saving Erekat’s life. And it wasn’t just right-wingers saying that. Michal Cotler-Wunsh, a moderate member of the Knesset from the Blue and White Party, asserted that prior to admitting him, Israel should have gotten the P.A. to agree to reciprocal humanitarian gestures, such as returning the bodies of slain Israeli soldiers being held by Hamas terrorists in the Gaza Strip.
One pragmatic answer is that for all of the antagonism between Israel and the P.A., in addition to the latter’s refusal to make peace, the day-to-day working relationship between them continues. There is a fair amount of security coordination going on that is partly aimed at reducing Palestinian attacks on Israelis, yet also focused on keeping Abbas alive against threats from his Hamas rivals.
But the real reason goes far deeper than that.
As much as Israel is depicted as a militarized state that is dominated and governed by its security establishment—Jewish values still play a crucial part in its decision-making. Being a Jewish state necessarily involves considerations that a purely utilitarian approach to life would reject.
The instinctual application of traditional Jewish values by the Jewish state’s secular government should not surprise anyone. Even when it will not advance Israel’s cause, behaving decently to those who would not reciprocate such a gesture is still the default position of any government of the Jewish state.
