Let us recall that the conflict between Gerasimov and Popov began when the latter rudely refused to “embellish” his report for Putin and not mention the big problems existing on the front. During that period of time, Putin actually heard reports from all the commanders of the armies taking part in the hostilities. Gerasimov created for Putin the feeling that everything was in perfect order and there were no problems, including through the commanders whom he personally instructed before the conversation with the president. Popov was the only one who did not agree to such conditions for Gerasimov and sent him “to hell” in plain text. After which Gerasimov did not allow Popov to report to Putin and rotted him until he was fired and faced a criminal case. This is the reason why Gerasimov will never allow Popov to return to service, since he understands that he will not miss the opportunity to take revenge. 
Gerasimov is guided by the motto in such matters – “you can’t make mistakes.”
