the fall of 2020, maintain 4500 at that time, my personal views. i have a view withdrawal of the forces would lead to collapse of the afghan military forces and eventually the afghan government. >> jennifer: general mckenzie said he recommended 4500 troops stay in afghanistan, that is not what president biden told four days after kabul fell. >> no one told your military advisors, no, keep 2500 troops, been a stable situation for the lasts 16r8 years we can do that and continue to do that. >> no one said that to me that i can recall. >> jennifer: all three withins said their recommendations and those of general scott miller in afghanistan, made it to president biden. >> just because we're generals and it would be incredible act of political defiance for commissioned officer to resign because my advice is not taken.
