regime change. So much for Kissinger. What then is left of the great Republican split? James Baker? Baker has said that ``the only realistic way to effect regime change in Iraq is through the application of military force'' but has argued for going first to the U.N. Now that we are, in fact, following the Baker recommendation, what is the basis for calling him an opponent? That leaves Colin Powell, supposedly the epicenter of internal opposition to the hard line on Iraq. Well, this is Powell last Sunday on national television: ``It's been the policy of this government to insist that Iraq be disarmed. ... And we believe the best way to do that is with a regime change.'' Moreover, he added, we are prepared ``to act unilaterally to defend ourselves.'' When Powell, the most committed multilateralist in the administration, deliberately invokes the incendiary U-word to describe the American position, we have ourselves a consensus. It turns out that the disagreement among Republicans was less about going to Iraq than about going to the U.N. It was a vastly overblown disagreement because even the most committed unilateralist would rather not go it alone if possible. Of course you want allies. You just don't want to be held hostage to their veto. And as the first President Bush demonstrated when he declared that the United States would liberate Kuwait unilaterally if necessary, the best way to get allies is to let others know you are prepared to go it alone and let them ponder the cost of missing the train. So what's left of the Republican revolt? Dick Armey, the sage of Lewisville, Texas, has been telling people that, sure, Iraq may have nuclear weapons, but so does France, and if you ask him, he's got more of a problem with France than with Iraq. The world now waits to see whether the Democrats will join Armey at the barricades.
