In February, the Taliban sanctuary of Marja in southern Afghanistan was attacked in the largest operation of the war. Last week, President Obama flew to Afghanistan and declared, “Our troops have pushed the Taliban out of their stronghold in Marja .... The United States of America does not quit once it starts on something.”

But what is that “something”? And, equally important, does Afghanistan’s president, Hamid Karzai, have to be a part of it?

The United States ambassador to Afghanistan, Karl Eikenberry, was guilty of understatement last fall when he told Washington that “Karzai is not an adequate strategic partner.” Still, getting rid of Mr. Karzai at this point wouldn’t be easy, and any major upheaval would clearly imperil President Obama’s plan to start withdrawing American troops next summer.

The Marja offensive, however, may have shown us an alternative approach to the war. For one thing, it demonstrated that our Karzai problem is part of a broader failure to see that our plans for Afghanistan are overambitious.

The coalition is pursuing a political-military strategy based on three tasks. First, “clear” the guerrillas from populated areas. Second, “hold” the areas with Afghan forces. Third, “build” responsible governance and development to gain the loyalty of the population for the government in Kabul. To accomplish this, the coalition military has deployed reconstruction teams to 25 provinces. We may call this a counterinsurgency program, but it’s really nation-building.

The problem with building a new and better Afghanistan is that, above the local level, President Karzai has long held the levers of political power by controlling provincial finances and leadership appointments, including those of police chiefs. Regardless of the coalition’s success at the district level, an obdurate and erratic Mr. Karzai is an obstacle to progress.

The success in Marja, however, changed the dynamics of the conflict. It now seems that the planned surge of 30,000 additional troops will likely achieve progress in “clearing and holding” Kandahar and other Taliban-controlled areas by mid-2011. At that time, the force ratio will be one coalition soldier for every three Afghan soldiers and policemen, and the Afghan Army will still rely upon us for firepower and moral support.

Ideally, we could then begin to withdraw major American units and leave behind small task forces that combine advisory and combat duties, leading to a new ratio of about one American to 10 Afghans. Not only would this bring our troops home, but it would shift the responsibility for nation-building to Afghan forces.

At the same time, we would have to pivot our policy in two ways. First, Mr. Karzai should be treated as a symbolic president and given the organizational “mushroom treatment” — that is, we should shut off the flows of information and resources directly to the national government.

President Ronald Reagan did something similar with another erratic ally, President Ferdinand Marcos of the Philippines. In February 1986, Reagan warned Marcos that if government troops attacked opposition forces holed up on the outskirts of Manila, it would cause “untold damage” to his relations with the United States — meaning the aid spigot would be turned off. When his countrymen saw that he was stripped of prestige and support, they forced Marcos into exile.

Second, the coalition must insist that the Afghan military play a primary role in the governance of the districts and provinces, including in the allocation of aid and the supervision of the police. We should work directly with those local and provincial leaders who will act responsibly, and cut off those who are puppets of Kabul.

This is happening, to some extent, in Helmand Province, site of the Marja battle, where the coalition has independent control over $500 million in reconstruction aid and salaries. We have been fortunate that the provincial governor, Gulab Mangal, while a Karzai appointee, has proved an innovative partner. But in any case, we know that coalition aid need not flow through Kabul.

Gen. Stanley McChrystal, the top American commander in the region, already seems to be considering this approach as the battle for Kandahar gains intensity. “One of the things we’ll be doing in the shaping is working with political leaders to try to get an outcome that makes sense” including “partnering inside the city with the Afghan National Police,” he told reporters last month.

Although isolating Mr. Karzai will strike many as a giant step backward, the truth is that we don’t have a duty to impose democracy on Afghanistan. The advancement of liberty doesn’t necessitate a “one person, one vote” system, as the 1.5 million fraudulent votes cast for Mr. Karzai in last summer’s sham election showed. We cannot provide democracy if we desire it more than the Afghans.

The Philippines — and South Korea as well — evolved into thriving democracies at their own pace, well after American aid helped to beat back the military threats facing them. It was enough to prevent the Communist takeovers and leave behind governments controlled in the background by a strong military. We didn’t spend tens of billions of dollars on material projects to inculcate democratic principles.

Similarly, a diminished Hamid Karzai can be left to run a sloppy government, with a powerful, American-financed Afghan military insuring that the Taliban do not take over.

Admittedly, this risks the emergence of the Pakistan model in Afghanistan — an army that has a country rather than a country that has an army. But we are not obliged to build a democratic nation under a feckless leader. We need to defend our interests, and leave the nation-building to the Afghans themselves.
