Which Bush era foreign policy will work best in the long-run?

I have written for today's (London) Times about three different Bush foreign policies...

• 'Neoconservatism' in Iraq;
• Multilateralism in Iran; and
• Realpolitik in Pakistan

I suggest that it's no longer impossible to believe that policy towards Iraq may produce the least troublesome nation of the three in a decade or two's time.  Space was limited but I could also have included Saudi Arabia in my list of Bush foreign policies - where outright appeasement has been pursued.
