When Your Next Door Neighbor Is Free Iraq

Interesting interview with Daniel Pipes about Abombnjihad v. Moussavi. I note this:
I am taken aback by the nearly complete absence of Islam in the discussion. One hears about democracy, freedom, and justice, all of which do play a role, but the key issue is the Iranian population’s repudiation of the Islamist ideology that has dominated its lives for the past 30 years. Should the regime in Tehran be shaken by current challenges, this will likely have profound implications for the global career of radical Islam.
That's what has struck me, too. I'm also thinking about the Bush Doctrine a lot these days. How much of what we're seeing in Iran is a direct result of having Free Iraq right next door?
