It is interesting that, amongst all the postings either blaming the USA for the problems in the Middle East or defending the actons of the USA, little is made about the role of the USSR and the political atmosphere of the Cold War.
As much as the USA supported regimes that appeared to oppose Communism, the USSR was instrumental in arming and supporting groups it thought were anti-US.
Most of the weaponry of the radical Arab states was Warsaw Pact in origin as much as the weaponry of the moderate states was provided by NATO. That was the nature of the the times when "My enemy's enemy must be my friend" became the ruling creed.
