Lots of folks think this nuke thing is good news for the GOP because it puts national security in play and diminishes the Foley stuff. As political analysis, I think that's probably right. But let's keep in mind that North Korea's nuke testing constitutes a failure of US policy. We can debate the details and the extenuating circumstances, but President Bush denounced the Axis of Evil five years ago and promised that he would do everything to keep its members from getting nukes. Well, North Korea just detonated one. Iran is well on its way to getting one. And Iraq, well, that's not quite the bright spot we hoped it would be.
The part I'd disagree with is the CW that national security works to the advantage of the GOP. Clearly, not anymore.
