What’s wrong with Axis of Evil? IMHO, it seems appropo...given the nation states it encompasses.
They are all evil for different reasons and need to be handled differently.
By lumping them all into one group we got the endless and useless discussions about how the Bush administration was willing to go to war with Iraq who had no nukes, but wouldn't go to war with NK or Iran who had them ... or soon will.
It is really stupid to have the President say things which either ties his hands diplomatically/militarily or makes him out to be going back on his words when he doesn't follow them.
Even if it is just a really crappy metaphor.
