Iran

First, it is fairly clear, as pgl notes, that Iran is not currently an imminent threat to the US. But what about the economic issues with the "Iranian Oil Bourse"?

Dr. Hamilton has a nice post addressing that issue: Strange ideas about the Iranian oil bourse

I agree with Dr. Hamilton, but I'm afraid the actual economic impact (or lack of economic impact) doesn't really matter. What matters is what Bush / Cheney think. Although the Bourse is inconsequential, an attack on Iran could have significant economic implications.

In my economic predictions for 2006, I included this caveat:

And for some reason I'm reminded of the fictional character Forrest Gump's quip: "Stupid is as stupid does." Lets hope the US is not stupid this time, otherwise $68/barrel WTI oil might look cheap, and my 2006 economic predictions wildly wrong.
