The US wars in Afghanistan, Iraq, Syria and Pakistan have cost the average American taxpayer $23,386 since 2001, according to a new analysis. The figure is triple the estimate put forth by the Pentagon.

The Pentagon’s most recent estimate, released in June this year, said the costs have amounted to $1.43 trillion over the last 16 years. That figure is closer to $5.6 trillion if you take into account the ongoing medical care for veterans of those conflicts, the war-related costs of the State and Homeland Security departments, as well as other costs that don’t fall under the Defense Department, a report released this week by the Costs of War Project at Brown University’s Watson Center shows.

“When wars end, the costs don’t stop, they grow,” Neta Crawford, the study’s author and co-director of the Costs of War project, told BuzzFeed News. “And these wars are being paid for on a credit card. That means that the next generation will have to pay for them.”

But the wars are not ending.

The staggering costs are going to continue to multiply after the Trump administration’s decision to increase the number of US troops in Afghanistan by 3,900. They will be joining the 11,000 already there to train and assist Afghan forces as they try to reverse the setbacks against the Taliban in recent years.

Under Trump’s budget for the 2018 fiscal year, direct US spending on the war in Afghanistan will top $840 billion, according to Anthony Cordesman, a military strategy expert at the Center for Strategic and International Studies.
