It'll make it a little harder for the Bushies to launch a pre-emptive strike on Iran. I think the Joe Sixpack reaction would be that Bush is going after the wrong target, again. Still, you never know the level of stupidity these jokers can reach in their holy mission.
I suspect the test will help Bush and Republicans, slightly, as the rally to the flag reaction battles against the wondering about what's Bush done to deal with this in the last six years.
Via Kevin Drum, there's a recap of how Bush screwed up Clinton's attempt to keep North Korea from getting nukes. Left out in that recap is the role Senator Jesse Helms played in stopping the US from giving them the reactors we promised. That guy did a lot of damage in his lifetime, and some of it hasn't been felt yet.
