Well that's not correct. Pakistan is more a U.S. ally than allied with China. India isn't going to need "Ukraine like assistance" as it has about 6 times the population of Pakistan, is wealthier, and has nukes. Pakistan/India would in no way be a proxy war, encouraged by us or the Chinese. It's a regional conflict, and in no way is one country seeking to conquer and take over the other. India is mostly Hindu, and doesn't need the headache of administering a Muslim population beyond the headaches it gets from its own Muslim citizens.
