The USSR trained and backed secular nationalist and socialist terrorists like the PLO and the IRA.
Iran funded local Shia terror organizations and the like and was independent of West and East.
America and the West made common cause with the fundamentalist Muslims out of which we saw the rise of al-Qaeda from the veterans of the Afghan war against the Soviets. If you want to call Latin American so called right wing death squads terrorists (I don't on a technicality) then they are from our side as well.
Not pretty but the truth never is.
Destro,
If you really want to blow a gasket, do a Freep search for the ISWR special report, "We Are The Next Target." You'll love that one.
