Some of the chatter on the internet is saying that it is the Chinese deep pockets which are making Russia cozying up to Pakistan a bit?
As for Russia wanting Americans out of Afghanistan--that's what Pakistan too want especially when whatever pitiful 'aid' is cut off to Pakistan. And when Americans leave Afghanistan then Pakistan's strategic options in Afghanistan will likely increase at the expense of India's. Am I right?
China might pressure Russia to be nice with Pakistan. We have seen RD-93 engine sales to Pakistan. China can bankroll Russian weapon sales to Pakistan. The question is whether they will.
Pakistani influence in Afghanistan will increase if Americans leave. Given geography India is no position to fight Pakistan one on one in Afghanistan. India can raise the costs of Pakistani intervention. the other option is an alliance with Iran and Central Asia to deny Pakistan control.
