Russia

It's an open question how much this [arms purchases from U.S. rivals] will end up affecting partners like India, but also countries like Indonesia and Vietnam who have these legacy relationships with Russia and are not going to give them up any time soon. In fact, there's an argument to be made that for America's Indo-Pacific objectives, you actually want these countries to maintain and build up a certain amount of military capability, and in some cases the U.S. cannot offer that capability.

The U.S.-India relationship is largely in sync, but Russia remains one major area of difference.
