Do you really believe in that?
Then you would bother to explain why Haftar is referred as "warlord" ,"marshal", "commander" instead of president of LNA?
Should we come to facts that he actually attained his position by misusing his position in military, aka: coup?
Or did you ever pay attention, you don't hear "Sarraj" as much as "Haftar" , you rather hear about GNA (or truly as Libyan government) vs Haftar and if not him, LNA and GNA would come into agreement quicker.
Or answer to this question would make it much more clear:
Who has hired foreigner paramilitary groups and militias, and received huge foreigner aid to assault and break ceasefires multiple times? you wouldn't answer as LNA, but "Haftar".
You may say GNA did so, but it was after Haftar started to crash them and sieged Tripoli with huge foreigner aid, as and GNA has done this as the last option, however it was Haftar's first option.
