I think if the CIA heads would have stopped to THINK about it... Sloane knows Irena Derevko, THE MAN... would never SELL anything rambaldi. The person who raided sd-6 to get a little jar of rambadli liquid, the person who, at every turn, sent a goon to stop sloane from getting rambaldi gear.. etc etc. So, why did the CIA believe that sloane would arrange this meeting? If sloane hadn't been in league with irena, he would have surely smelled a rat. I think the CIA shoulda seen something was up... if nothing else someone shoulda brought up.. "hey ya know that guy that does all sloane's bidding... he worked for derevko."
