A recent example is Brett Stephens, a columnist for the New York Times. In an op-ed entitled "Abandoning Afghanistan Is a Historic Mistake," Stephens writes:
The U.S. has lost fewer than 20 service members annually in hostile engagements in Afghanistan since 2015. That's heartbreaking for those affected, but tiny next to the number of troops who die in routine training accidents worldwide.
Yes, it's heartbreaking and the number of deaths might be "tiny" compared to other things but the point that Stephens is making, whether he realizes it or not, is that it's worth sacrificing the lives of those 20 men every year for the indefinite future.
The important question is: What are those soldiers being sacrificed for? According to Stephens, they are being sacrificed to prevent the Taliban from retaking control over Afghanistan. He points out that if the Taliban end up winning Afghanistan's civil war, that will mean tyranny for the Afghan people.
