For all leader in the modern world where only human could cause other species to extinction and only human could do serious damage to environment as well as massacre just to serve their ideology, I think leaders should be apart from all supernatural belief as well as God.
Or to simply put, leaders should be atheists. Because you are the leader for human’s activities not for religion’s or goodness’s sake.
Your decision could improve people’s life or could do serious harm to them. Its only your decisions that count. So please don’t do any ceremony related to human’s life and accuse to God when shit happened.
