I definitely think it ends the conflict going on now. As far as the oligarchs doing anything i dont see that happening because they were the ones to put him in power thinking they could control him.After he became president he took them to the room where stalin used to execute people and told them they could earn but he was in charge now. Now if he was killed that power would leave a vacuum so theres really no telling what will happen just like we didn’t realize executing saddam would lead to isis.
