Ah! We are a fickle blame-America isolationist, now aren't we?
After all (as I would point out if I were a blame-America isolationist) it was Eisenhower who, shortly after entering office, reversed Truman's adamant refusal to agree to a British sponsored coup against the Iranian government of Mohammed Mosaddeq.
Since the current global Jihad identifying America (the "Great Satan") as a principal target originated with the Iranian Revolution (by which even Shia hating Sunni militants openly admit they were inspired) which revolution was itself a reaction to the Western, modernist governance of the Shah following Mosaddeq's removal, I would, if I were a blame-America isolationist, blame Eisenhower rather than absolve him.
Well, according to the facts as you have laid them out, how could you absolve Eisenhower? What U.S. national interest was at stake in Iran in the 1950’s?
