This is the Dream

"We are awaiting aggression by Israel and any supporters of Israel. We will make it a decisive battle and get rid of Israel once and for all...this is the dream of every Arab."

Gamal Abdel Nasser, 1959

Scenario
Despite lending substantial diplomatic and economic support to nations such as Egypt and Syria during the height of the Arab Nationalist Movement in the 1960's, the Soviet Union was nevertheless reserved when it came to military support. This proved a poor decision; for the lack of modern military hardware and planning proved decisive when the USSR's primary regional allies were defeated by Israel following the Six-Days War. What if, however, the Soviets were more willing to lend the Arabs the support they needed the most...

POD
Following the fall of Nikita Khrushchev in the Fall of 1964, the Soviet Union's new leadership troika (composed of Leonid Brezhnev, Alexei Kosygin, and Nikolai Podgorny) began to initiate a considerable shift in foreign policy that deviated far from the one employed by their predecessor. Rather than militarily supporting their allies in Africa and Western Asia outright as the Khrushchev regime had done, the troika instead opted for merely economically supporting states such as Syria and the United Arab Republic whilst diverting surplus military hardware to independence movements in South-East Asia as a means to more readily fight against American and Chinese influence, particularly in Vietnam. In this timeline however, the troika never opts to completely remove the socialist-nationalist states in Africa and the Middle East from their defence network; instead, they continue to supply the predominantly Arab nations aligned to them with the training and hardware they needed to oppose both states that fell under the spectre of American-influence, and their own regional rival; Israel.
