This Friday we’ll open with another great column from Victor Davis Hanson, on the folly of half-measures: Our Reptilian Brains.

Here our greatest weakness has been the half-measure: the need to consult all the ill-informed in the Middle East rather than a few of sound judgment; the good intention not carried out; the threat to thwart evil reduced to lecture and then whine rather than audacious action. We worry too much about the one-day response to our use of force and not the 100-hour gradual appreciation that we are winning. Shooting looters to restore order and save the Iraqi infrastructure would have saved lives and enraged the world for a day. But pictures of subsequent strolls in parks and Iraqis stringing telephone wire and pouring cement would have impressed it far more.

Storming Fallujah would have begotten Jenin-like hysteria, condemnations from mullahs and imams, and cries from John Kerry — for a day or two — but begrudging respect inside Iraq that thousands of insurrectionists (among them hated Baathists) were dead or scattered, and it was safer now to be against Saddam’s remnants than with them. The world is not talking publicly as it did a few weeks ago about the injustice of the murderous Sheik Hassin’s departure to paradise, but rather murmuring in private that it saved lives and was long overdue.

It is tricky, risky, and downright dangerous to kill or capture Mahdists inside the Holy City of Najef — and our presence will incite demonstrations throughout the Islamic world. But if Mr. Sadr flees Sadr City, flees Karbalah — flees everywhere we attack to find him — his hordes will melt, and those who loudly castigated us for overreaction will quietly praise our sobriety and resolve. In fact, they are already beginning to. Brave and extremely able American soldiers are systematically dismantling his militias even as the world screams about Abu Ghraib. Again, the key is to win and give all credit to the Iraqis.

Such a recognition of human calculation does not constitute approval for realpolitik or the logic of mere force; rather it is an appreciation that morality should be defined as action rather than empty words or good intentions. In each case, protecting the innocent from looters, ridding Iraq of Baathist killers, and stopping fanatics from hijacking Shiite hopes for democratic prominence was the right thing to do — but impossible without the use of guns and steel. While most people simply wish to associate with victory, we need not pander to that base emotion, only appreciate it and indeed co-opt it for a better purpose.

The only thing worse than the amoral use of force is the failure to act when it is the only right and moral thing to do. In short, I think our sole serious mistake in this war is that we have forgotten the lessons of history, the essence of human nature, and what constitutes real morality. Small armies, whether those of Caesar, Alexander, or Hernan Cortés can defeat enormous enemies and hold vast amounts of territory — but only if they are used audaciously and establish the immediate reputation that they are lethal and dangerous to confront. Deterrence, not numbers, creates tranquility and the two are not always synonymous.

It’s hard to do justice to VDH’s argument with a short quote; go ye and read of the whole thing.
