Via Matt Yglesias (who wrote about the Richardson candidacy earlier this week) comes this Richardson-penned column:

The recent tentative agreement with North Korea over its nuclear program illustrates how diplomacy can work even with the most unsavory of regimes. Unfortunately, it took the Bush administration more than six years to commit to diplomacy. During that needless delay North Korea developed and tested nuclear weapons — weapons its leaders still have not agreed to dismantle. Had we engaged the North Koreans earlier, instead of calling them “evil” and talking about “regime change,” we might have prevented them from going nuclear. We could have, and should have, negotiated a better agreement, and sooner.

Then on to Iran:

No nation has ever been forced to renounce nuclear weapons, but many have chosen to do so. The Iranians will not end their nuclear program because we threaten them and call them names. They will renounce nukes because we convince them that they will be safer and more prosperous if they do that than if they don’t. This feat will take more than threats and insults. It will take skillful American diplomatic leadership.

Matt continues with the “He’d make a good cabinet secretary” theme:

I don’t know what kind of campaign strategy this is, but maybe he can be Secretary of State or some kind of special envoy.
