President Reuven Rivlin said Sunday that the failures of the Yom Kippur War were brought on by a lack of self-criticism - something that we must not let repeat itself today.Speaking at the official memorial ceremony for the fallen of the Yom Kippur War at Jerusalem's Mount Herzl, Rivlin said, "The Yom Kippur War happened, among other reasons, because the various watchdogs of democracy were too full, and did not bark at night."Rivlin said that "the Israeli leadership must be exposed at all times to difficult questions. We don't have to wait for a war or operation. The wisdom is in a constant probing by the oversight committees, the media and the entire public."Rivlin said that it was the public's obligation to ask difficult questions of its leadership.
