Over the next few years there will be many assessments of the eight years of the George W. Bush presidency in regards to foreign policy. I think the honest ones will see that there was the period where the views of Cheney held sway in foreign affairs and the latter period where the views of Condi Rice were paramount. The two periods aren't divided accurately by first term/ second term. Frankly, I await the books by Cheney and Rumsfeld more than the book by GWB.
Now it's very safe to say that John Bolton was more a Cheney guy than a Rice guy. Given that, it's interesting to read his op-ed here about Obama's approach to Iran.
