“I have no idea what the U.S. strategy is for Afghanistan,” former U.S. Air Force General Counsel, Mary Walker, said to me at a dinner a decade ago when I asked why is America in Afghanistan, and what is our long-term objective.

Imagine being on a soccer field with all the players and no goalposts for either side. Which way to run? How to win?

Another question.

Why have American politicians, across three presidencies, spent close to a trillion dollars in Afghanistan and sent young people off to fight and die in a war with no clear mission?
