Perhaps the most blatant example of the bankruptcy of conventional wisdom at the Pentagon came from retired General David Petraeus in an interview with PBS reporter Judy Woodruff in June of 2017. Petraeus spoke of a “sustainable, sustained commitment” to Afghanistan and the need for a “generational struggle” with Islamic terrorists who are located there. Comparing Afghanistan to the U.S. commitment to South Korea, he hinted US troops might be there for 60 or more years (though he backtracked on the 60-year figure when challenged by Woodruff).

Here’s a telling excerpt from his interview:

We need to recognize that we went there [Afghanistan] for a reason and we stayed for a reason, to ensure that Afghanistan is not once again a sanctuary for al-Qaida or other transnational extremists, the way it was when the 9/11 attacks were planned there.

That’s why we need to stay. We also have a very useful platform there for the regional counterterrorist effort. And, of course, we have greatly reduced the capabilities of al-Qaida’s senior leaders in that region, including, of course, taking out Osama bin Laden.

But this is a generational struggle. This is not something that is going to be won in a few years. We’re not going to take a hill, plant a flag, go home to a victory parade. And we need to be there for the long haul, but in a way that is, again, sustainable.

These statements are so wrongheaded it’s hard to know where to begin to correct them:

The US military went into Afghanistan to punish the Taliban after 9/11. Punishment was administered and the Taliban overthrown in 2001, after which the US military should have left. The decision to stay was foolish and disastrous. Extending a disastrous occupation is only aggravating the folly. “Transnational extremists”: According to the US military, the Af-Pak region has exploded with terrorist elements, and indeed Petraeus and his fellow generals count twenty or more factions in Afghanistan. In sum, rather than weakening Islamic extremism in the area, US military action has served to strengthen it. “A very useful platform”: The US has spent roughly a trillion dollars on its eighteen-year-old war in the Af-Pak region. The results? The Taliban has increased its hold over Afghan territory and Islamic extremism has flourished. How is this “very useful” to the United States? A “long haul” that’s “sustainable”: What exactly is “sustainable” about a war you’ve been fighting – and losing – for nearly two decades? Leaving aside the dead and maimed troops, how is a trillion dollars a “sustainable” price for a lost war? No “victory parade.” At least Petraeus is right here, though I wouldn’t put it past Trump to have a military parade to celebrate some sort of “victory” somewhere.

It appears President Trump is finally fed up, suggesting a withdrawal of troops from Syria as well as a force drawdown in Afghanistan. But it appears Trump is already caving to pressure from the Pentagon and the usual neo-con suspects, e.g. National Security Adviser John Bolton suggests US troops won’t withdraw from Syria without a guarantee from Turkey not to attack America’s Kurdish allies, which, according to the New York Times, may extend America’s troop commitment by “months or years.”

Trump needs to realize that, if it were up to the Pentagon, America today would still be fighting the Vietnam War, rather than working closely with Vietnam as a partner in efforts to counterbalance China.

The Pentagon’s conventional wisdom is that US troops, once committed, must never leave a region. Victory or defeat doesn’t matter. What matters is “sustaining” a “sustainable” commitment. Hence troops are still in Iraq, still in Afghanistan, still in Syria, still in 800+ bases around the world, because any withdrawal is couched as surrender, a display of weakness, so says America’s military “experts.”

The US doesn’t need a “sustainable, sustained commitment” to the Middle East or Central Asia or anywhere else for that matter, other than right here in the USA. We need a sustainable, sustained commitment to a better health care system. To better roads, bridges, airports. To affordable education. To tax cuts that actually help the middle class.

When it comes to “generational struggles,” David Petraeus, let’s fight for a better America, not for sustaining troops in lost causes around the world.
