Mark Safranski springboards off of Tom's Only Ahmadinejad can go to Washington with his own Is Ahmadinejad the 'New Nixon'?. Not only is Mark's post (and the subsequent one) a nice survey of this issue, but he has a lot of great analysis and information.

One beef though: Mark finds Tom's analogy to be 'inexact'. Fine, buddy. It's easy to take apart a nice analogy with 'analysis' and 'facts'. Where's you narrative contribution, Mark? Use your left brain. Use your zen. Be the analogy! ;-)
