Interesting. So you think morality is quantifiable? Like it's fine to violate X amount of human rights but not X + 1. I'd like to hear your criteria.
"genocide" of Muslims via constant war-waging; "ethnic cleansing" of native Americans; natural resource exploitation on a global scale; "modern day slavery" (i.e. extreme capitalism) both domestically by trapping workers into lifetime debts, and overseas by outsourcing to sweat shops; "deadly global pathogen release" by politicising pandemic responses while failing at it.
Rivalry states smear each others all the time. Also no contender for hegemony is morally superior than another.
Contemplate Nazi Germany winning WWII, or Soviet Russia winning the Cold War. Your contention doesn't stand up to history's lessons.
