Six-Day War
On May 26, 1967, the Central Intelligence Agency stated, "The Israelis... If they attack now they... would still be able to drive the Egyptians away from the entrance to the Strait of Tiran, but it would certainly cost them heavy losses of men and matériel". A few days before the war, Israel believed it could win a war in 3 to 4 days. The Americans and the British believed that would take 7 to 10 days.
