"Bush is pretty much following the Sharansky formula."
I think the "formula" of the Bush Doctrine--support for democracy, freedom and peaceful secure relations with neighbors--has been around a lot longer than Sharansky.
What is new is that we have a President once again who means it and believes it.
I think you are right. But the Sharansky model in his book allowed Bush to confirm his instincts by reading them from a writer he respects.
