At Wednesday night’s Yad Vashem ceremony marking the start of Holocaust Remembrance Day, Prime Minister Benjamin Netanyahu – if past speeches are a gauge – will touch on the theme that one of the lessons of the Holocaust is that Israel can, in the final analysis, only rely on itself.

If, as the Russians, Syrians, Iranians and even the Americans said on Monday, Israel was indeed responsible for the predawn attack on the T-4 airbase near Homs in Syria, it is a sign that Netanyahu means what he says every year in those speeches.
