Life Support?

Yglesias singles out a critic of Bill Clinton:

Probably the most ridiculous remark comes from Steven Hayes, who says “John Bolton is right, this is a lifeline to a regime that is a terrorist regime that has proliferated nuclear technology.” Think about that metaphor. Does Hayes really think that Clinton going to Pyongyang or not is the difference between the DPRK collapsing or not? Why would that be? I suppose this is consistent with the general neocon belief that symbolic, expressive activity on the part of Americans is the key factor in determining events abroad but it seems like a mighty extreme version of it.
