When speaking of governments trampling on human rights, several immediately jump to mind as examples. Along with the US itself, it also employs, supports, arms and funds, ME nations as proxies, there are primarily Israel, Turkey, Saudi Arabia, as well as the Egyptian dictatorship (omitting the Deash/IS depraved criminals).
There are other "global governments" that trample human rights and commit war crimes doing so, but few can and do influence war and conflict as much as those mentioned. Turkey under President Erdogan and his relentless pathological war against Kurdish national aspirations or even a modicum of self-rule inside and outside Turkey.
Israeli ethnic cleansing of Palestinians, half century brutal occupation and illegal colonization of Palestine and numerous war crimes.
Saudi war crimes against Yemen's civilians and support for kindred Sunni terrorists, Daesh et al.
Egypt's military coup overthrowing the elected government and current dictatorship committing mass killings, kangaroo court trials, wholesale repression of dissidents and more.
The depraved group of four plus one, driving war, displacement and deaths of millions.
Turkish imprisonment of Kurdish leader Abdullah Ocalan, sentenced to death, commuted to life, is a political imprisonment, very like Israel's imprisonment of Palestinian leader Marwan Barghouti.
Peace can only be achieved through negotiations and justice, not wars - wars achieve profits and power for the connected few and death for most....
There is one (relatively) bright spot in this nightmare.....if only the Kurds aren't betrayed by the West yet again!
