QUESTION: IS OBAMA/ARAB SPRING : DUBYA :: REAGAN : GHWBUSH/THE FALL OF THE USSR?

QUESTION: Is Reagan: GHWBush/fall of the USSR :: Dubya : Obama/"Arab spring"?

Yes: iff the Arab spring doesn't lead to jihadist/Iranian-style takeover instead of more self-determination/democracy.

UPDATE:

IF THE ARAB SPRING TURNS OUT TO BE MORE LIKE THE IRANIAN REVOLUTION - WHICH SEEMS MORE AND MORE LIKELY, THEN THIS FORMULA WOULD BE MORE TRUE:

OBAMA : ARAB SPRING :: JIMMY CARTER : IRAN & TRUMAN : CHINA.
