13 April National Review commentary - Dead-end Debates: Critics Need to Move On by Victor Davis Hanson.

Currently there are many retired generals appearing in frenetic fashion on television. Sometimes they hype their recent books, or, as during the three-week war, offer sharp interviews about our supposed strategic and operational blunders in Iraq — imperial hubris, too few troops, wrong war, wrong place, and other assorted lapses...

Imagine that, as we crossed the Rhine, retired World War II officers were still harping, in March, 1945, about who was responsible months during Operation Cobra for the accidental B-17 bombing, killing, and wounding of hundreds of American soldiers and the death of Lt. Gen. Leslie McNair; or, in the midst of Matthew Ridgeway's Korean counteroffensives, we were still bickering over MacArthur's disastrous intelligence lapses about Chinese intervention that caused thousands of casualties. Did the opponents of daylight bombing over Europe in 1943 still damn the theories of old Billy Mitchell, or press on to find a way to hit Nazi Germany hard by late 1944?

More troops might have brought a larger footprint that made peacekeeping easier — but also raised a provocative Western profile in an Islamic country. More troops may have facilitated Iraqization — or, in the style of Vietnam, created perpetual dependency. More troops might have shortened the war and occupation — or made monthly dollar costs even higher, raised casualties, and ensured that eventual troop draw-downs would be more difficult. More troops might have bolstered U.S. prestige through a bold show of power — or simply attenuated our forces elsewhere, in Japan, Okinawa, Korea, and Europe, and invited adventurism by our enemies. Too few troops were the fault of the present Administration — or the chickens that came home to roost after the drastic cutbacks in the post-Cold war euphoria of the 1990s.

"Troop transformation" has become equally calcified. We know the script. Pensioned Army and Marine generals appear ever more ubiquitously to assure the public that we have near criminally shorted ground troops. They alone are now speaking for the silenced brave majors and dutiful colonels stuck on the ground in Afghanistan and Iraq with too few soldiers — as their four-star Pentagon brass sold out to Mr. Rumsfeld's pie-in-the-skies theorists in Washington.

Maybe — but then again, maybe not. The counterarguments are never offered. If hundreds of billions of dollars were invested in sophisticated smart shells and bombs, drones, and computers, to ensure far greater lethality per combatant, then must traditional troop levels always stay the same? How many artillery pieces is a bomber worth, with ordinance that for the first time in military history doesn't often miss? Has the world become more receptive to large American foreign bases? Or depots to housing tens of thousands of conventional troops and supplies? And did lessons of the Balkans and Afghanistan prove the need for far more ground troops and traditional armor and artillery units?

The point is simple: Somewhere between the impractical ideas that the U.S. military was to become mostly Special Forces on donkeys guiding bombs with laptops, or, instead, a collection of huge divisions with tanks and Crusader artillery platforms, there is a balance that the recent experience of war, from Panama to the Sunni Triangle, alone distills. And it isn't easy finding that center when we had enemies as diverse as Slobodan Milosevic, Mullah Omar, Osama bin Laden, and Saddam Hussein.
