Is there evidence that the CIA as of recent had an inaccurate view of the situation in Afghanistan? I couldn’t find it in the article but it could be.
What happened in Vietnam was that the CIA had a very accurate view of the situation but the military loudly and repeatedly claimed everything was going well. Depending on the day, LBJ either wanted to believe that or felt he had to maintain the fiction in order not to lose in ‘68. I wouldn’t be surprised if history rhymes here.
