I recently read a book on the failure of Israeli intelligence to anticipate the Yom Kia rpur war. One thing that got my interest was that the Israelis had been informed by a highly placed Egyptian spy that the Egyptians planned to attack on the 15th of May. As response, the Israelis initiated the Blue-White counter-operation which consisted of training exercises for reservists, tank reinforcements in the Sinai and the Golan and a series of ramping up of military procurements. These preparations began in April and continued until the beginning of August when they were discontinued at a cost of 30 million dollars.
Whether this May war scare was real or a bit of misinformation by the Egyptians is still a bit of on open issue. One theory that was floated by the Israeli intelligence community is that there was an actual countdown to war in May but that the Soveits stopped it to prevent the Brezhnev-Nixon meeting in June 1973 from being affected. Assuming this theory is what actually happened, what would the affects of a Egyptian-Syrian attack during Blue-White that isn't vetoed by the Soviets be ?
