in Myanmar or Tibet US has no strategic interests

I'd say it does: to strategically weaken China, the same way Russia/the Soviet Union was 'encircled'. I rather think inaction there is a sign of real weakness, a weakness that was meant to be clouded with the war in Iraq, and a weakness many European governments still can't see when following politics of vassaldom.

Would the US even attempt to organise a velvet revolution in Pakistan, I am curious whom you think they'd support as leader. Do you think the US could bet on Sharif?
