New post-9/11 wars cost estimate: $8 trillion

The US military role in Afghanistan is over, but the costs will continue to mount as the forever wars rage on.

In anticipation of the 20th anniversary of the 9/11 attacks, Brown University’s Costs of War Project on Wednesday published an “updated estimates on the most comprehensive and widely-cited assessments of the financial and human costs of the past 20 years of war.” 

The Project’s last update in 2019 estimated that the post-9/11 wars cost more than $6 trillion and 800,000 lives. But its new assessment has found that between 897,000 and 929,000 have been “directly killed,” while the United States has appropriated and obligated to spend more than $8 trillion. 

The latest report comes as President Biden ended America’s 20-year war in Afghanistan, which was estimated to have cost U.S. taxpayers $2.313 trillion, while Washington has so-far spent $2.058 trillion on the wars in Iraq and Syria. But while the U.S. war in Afghanistan is now over, the so-called “forever wars” are still ongoing throughout the region in places like Yemen and the Horn of Africa, where the Project estimates that roughly $355 billion have been spent. 

The Project’s estimate includes the cost of veterans’ care from 2001 to 2050, which according to its report from August, will cost U.S. taxpayers between $2.2 and 2.5 trillion. 

“Many people don’t know the extraordinary toll these wars take, not just the cost of deploying troops, not just the cost in terms of human lives, but the costs in terms of benefits and in terms of our obligations for decades to come,” said Rep. Ro Khanna (D-Calif.) in prepared remarks for the Cost of War Project’s online event launching their new findings. “Had we not stayed in Afghanistan for 20 years we would have had enough money to provide a free college education or vocational school for every American.”

Rep. Barbara Lee (D-Calif.), also in prepared remarks for the event, noted that she voted “no” on the authorization to use military force in Afghanistan after 9/11 (she was the lone dissenting vote).

“I voted no because I feared the consequences of giving the president, any president, open ended power to use military force anywhere against anyone or any nation,” she said, adding, ”Those consequences have been devastating.”

Ukraine's 'Busification' — forced conscription — is tip of the iceberg

Europe

Busification” is a well-understood term in Ukraine and refers to the process in which young men are detained against their will, often involving a violent struggle, and bundled into a vehicle — often a minibus — for onward transit to an army recruitment center.

Until recently, Ukraine’s army recruiters picked easy targets. Yet, on October 26, the British Sun newspaper’s defense editor, Jerome Starkey, wrote a harrowing report about a recent trip to the front line in Ukraine, during which he claimed his Ukrainian colleague was “forcibly press-ganged into his country’s armed services.”

Hegseth dropped big Venezuela easter egg into Quantico speech

Latin America

On September 30, Secretary of Defense Pete Hegseth summoned nearly 800 of America’s military generals, admirals, and senior enlisted officers to Quantico, Virginia on short notice. Though the unprecedented event was written off by many as a political stunt, a month later, it is clear the gathering was more important than many realized.

Of particular note were the speeches delivered by Hegseth and President Donald Trump which offer the clearest articulation yet of how the Trump administration thinks about and hopes to use military power. What’s more, taken together, the two sets of remarks appear to foreshadow both the current U.S. military build-up underway in the Caribbean and what might be on the horizon as U.S. operations there and elsewhere continue.
