No country has been more deeply enmeshed with brutal dictatorships around the world than the US. Case in example is Pakistan.
It was Pakistan that initiated the next great genocide after the Nazis during WW2. Its brutality in erstwhile East Pakistan (now Bangladesh) is very well documented. Can you guess who was Pakistan’s primary ally during those times? Yes, the human rights-loving US, which sent a Carrier Battle Group to intimidate India and protect Pakistan. If the Russian Navy did not block the CBG in the Indian Ocean, the US would have come in direct military conflict with India. Still, America’s actions delayed Indian military response, possibly causing millions of excess deaths of Bangladeshi people at the hands of Pakistan.
No US administration has had much to say about the extremely violent campaigns of ethnic cleansing Pakistan has carried out (and is still carrying out) against minorities of all shades inside Pakistan. The Ahmadis - Muslims who are hated by the dominant Sunnis - have been particularly at the receiving end, but other minorities, especially Hindus have long been brutally persecuted in Pakistan, to little more consequence than a gentle slap on the wrist by the great democracy and human-rights loving US of A.
The US literally paid Pakistan billions to kill American soldiers in Afghanistan - a practice that the much-hated Trump put an end to. Whatever you say about him, he had the guts to call a spade a spade and call Pakistan out for what it is - a terrorist sinkhole responsible for inflicting enormous misery on American and Afghan people.
If the US is vehemently against Chinese excesses in Xinjiang, I understand that as part of the power contest between the US and China. If US-China relations improve, the Xinjiang situation will be quietly buried, only to be resurrected when relations tank again.
So I think America’s commitment to human rights and democracy around the world is a self-serving travesty. It is sad but ‘human rights and democracy’ has been weaponized to serve the policy objectives of the West and carries no real moral authority to anyone anymore. Sad but true.
