I looked for the 2018 interview you mentioned, but came up short. I did find that in October 2020, he called Trump 'the most flawed person' he's ever met.
You seem to be misinformed. General Kelly was not involved in the planning of the withdrawal from Afghanistan. By the time the Doha Agreement was signed in 2020, Kelly was no longer in a government or military role that would involve him in this process. General Milley contributed to the discussions and provided military counsel, but neither he nor Kelly was responsible for the overall planning and implementation of the withdrawal.

Kelly said a whole bunch of nice things about trump in the interview. He didn’t use many of his ideas because he was an idiot apparently. The fact that you use him as an example is ridiculous. Which is it gen Kelly. Is he smart, brilliant and more knowledgeable than you would ever think. Is he attacked by the media for things that just aren’t true. Or. Is he a fascist. Why? Why would you believe him. Seriously how many debunked claims like this must there be before you don’t believe a damn thing. We listed 50 false claims about Trump on the board a month ago. 50! Every politician in the Dem party called him a liar before he switched sides.
