My main problems with your so called "background info" are that it's mostly a opinion, extremely onesided or just completly wrong. All those things are considered bad for questions here. Also, words like extremely should not be used that way,
Let me try to correct your info-part (I don't know much about Pakistan, so i changed less there):
India(almost everything here was just wrong):
India is a nation with neoliberal policies that lately cut funding for healthcare, their social system and the enviromantal programs. It moves towards secularism, although the goverment still has strong connections to several religios groups, and it has a large refugee intake. It is also the world's largest democracy, with a much higher voter turn out than the US itself, and a constitutional clause requiring polling stations within 2 km of each voter.
Pakistan on the other hand is conservative. They have a very laissez-faire economic policy, few and underfunded social programs for the poor. They were conservative socially, having persecuted minorities to the point that minorty percentage has gone from ~22% upon independence (1947) to ~2% today. This includes a genocides of Hindus, Sikhs, Ahmaddhis, Bangladeshis, etc. that have killed several million. As for democracy, it has recently gotten rid of it's last dictator and democratically elected a Prime Minister.
The Democratic Party of the US has been known for their recent progressivization, with several new members like "the squad" (Alexandia Ocasio-Cortez, Ilhan Omar, Ayanna Pressley and Rashida Tlaib) as well as seasoned politicians like Bernie Sanders openly calling themselves Democratic Socialists. They often claim to base their party on human rights, calling for foriegn aid to various nations, and the ban of arms sales to human rights violaters like Saudi Arabia, etc.
The very same Democratic party has been consistant in the support of Pakistan.
(everything after this sentence are accusations without any sources to back it up)
I just want to start by saying that I will not equate the human rights violations of Pakistan to the Republicans, as Republicans have caused inequality, violence and human rights violations against minorities, but state-sponsored persecution (at least in recent history). While there are several racists in the party, it would be unfair to stereotype them by the actions of a few. That being said, Republicans do tend to not care as much about human right issues, with Trump pushing to increase arms sales to Saudi Arabia. Republicans are however, extremely anti-Socialism. We've all heard them say "America will never be a socialist country." They have been quite clear in their efforts to stop the spread of such ideologies.
The very same Republican party has often supported India, with Trump being quite friendly with Modi. Republicans have pushed to sell arms to the Indian Army, as well as providing aid. Several Republicans have been quite outspoken about why the US should stop supporting Pakistan.
