In the aftermath of 9/11, America's political leaders lept to action based on, what turned out to be, a series of misplaced and untested assumptions.

Critical missteps came with a human cost for both American soldiers and Afghan civilians.

In this episode of None Of The Above, IGA's Mark Hannah sits down with Michael Cohen and Monica Duffy Toft of the Afghanistan Assumptions Project to analyze the key beliefs and decisions that shaped America's longest war.
