The Bush administration has made an offer to North Korea on the nuclear issue that sounds suspiciously, no exactly, like the offers they derided Clinton for making. See The Poor Man: Steady Leadership Watch for details, necessary flip-flop comments, general and earned snark.
I want to highlight a slightly different aspect of this development. The Bush offer is likely to be seen by N. Korea — more importantly, by other US adversaries (think, “militant Iraqis”) — as a sign of weakness: the Bush administration, sagging in the polls, goes shopping for foreign policy deals that can be marketed domestically as “victories'.
A foreign perception of a weak, anxious, maybe desperate, Administration eager to make deals for short term political gain means that our adversaries will drive the hardest bargains they can, thinking that the deals on offer will never be this good again. As a general matter, that's bad for the US whether this foreign perception is right or not, as we'll either have to give up more, or won't be able to come to agreement.
It's not just strong Presidents who are dangerous; weak Presidents are dangerous too, just in different ways.
