So much for "The American Conservative".
Lets be real. When Truman got into Korea and Johnson got into Vietnam they intended a negotiated settlement and the end game in Afghanistan looks pretty much the same.
We fight wars under international law and United Nations rules with total World War II style victory out of the question.
The military force in Afghanistan right now the USA is part of is called the “International Security and Assistance Force” under United Nations authorization.
The least conservative idea in existence today is the idea that invading other countries can help either them or us.
