At the time, in the summer of 1970, however, when "Israel complained to Washington that the Egyptians had breached the agreement, Ray Cline, the head of the State Department intelligence unit…told the White house that the Israeli complaint was baseless. When Israeli Ambassador Yitzhak Rabin told his military attache, General Eli Zeira, what had happened, Zeira immediately asked Tel Aviv to send him a photographic interpreter and a set of aerial photographs showing the Egyptian deployment. These duly arrived in Washington and Zeira was summoned to the White House, where he laid out the evidence before President Nixon. Nixon, angry with Cline, then ordered the Pentagon to remove its veto on several categories of weapons the Israelis had asked for during the preceding months."
Good information Phil. I was not interested in politics at that time so a lot of the details are new to me.
