Russia doesn’t have a choice. Few years back I predicted in this forum that Putin’s ego will result in Russia becoming side kick of China. Unfortunately it happened much faster than I anticipated. Question is how quickly we can replace our Russian equipments?? It will be terribly painful and expensive!!
The opposite. Russia holds all the cards.
If Russia doesn't get what it wants peacefully, they can get it militarily. They have a lot of options. Let's assume all three powers decide to become their enemies.
1. Europe can be dealt with via insurgencies in the Baltics and the Balkans, even Africa, where Wagner has been creating problems, the French in particular.
2. China can be dealt with through multiple ways. They are militarily inferior to the Russians today. Parity may only be achieved by 2030 before aiming for a superiority after 2035, so that's more than a decade away, not counting Russia's attempts at militarisation. If the Russians properly militarise again, then China won't achieve parity for a very long time. So China cannot get into a direct conflict with Russia today. Which means, the Russians can always start an insurgency in Xinjiang unchallenged.
In both cases, neither Europe nor China are capable of initiating war with Russia due to different reasons. If they do prefer to go to war, then that's fine with Russia, they will have no choice anyway.
3. This one is the ultimate. The various means they have to pull the US into conflict with others is insane. Two of their patsy countries are NoKo and Iran. All the Russians have to do is arm and fund them enough to start creating problems in East Asia and the ME, enough to drag the US in. No/SoKo can drag the Chinese in as well.
They have other means too, like making space unusable, only nuclear-powered satellites can function reasonably well in such an environment. They can cut internet connections via taking out submarine cables. And worse comes to worst, they can start destroying oil pipelines via non-state actors and severely disrupting the energy market. This is basically a Russia vs the world scenario.
Why? Any attempt at curtailing the Russian economy beyond what's already done will see them resorting to hostilities, that's the no-choice bit. And they have plenty of cards for that.
As for our dependency on Russian weapons, it's not gonna go away for a very long time. We have three areas where we depend on them. One is outright purchases of entire systems, like the T-90 and the S-400. That's gonna dissappear well before 2030, at least in terms of contracts signed.
The second is spares and supplies. With Russia militarising, they plan to move spares and supplies for not just the Indian market but also the global market. It's unlikely to be 100%, like the MKIs, but it will be enough to end more than 90% of the current imports from Russia by 2030.
The third is a bit sticky. It's R&D and MLUs. Cooperation here is not expected to end until 2035-40. We gotta buy new Brahmos missiles, production of which will go on for at least 10+ years, at least until 2035-40. And then we have a whole string of aircraft and helicopters that need upgrades; MKI, Mig-29K, IL-76/78 and Mi-17. There's the Talwars and Vikramaditya upgrades. They are involved in other R&D programs within DRDO as well, the biggest of which is SSBNs.
So the greatest dependence is this decade. But by 2030-35, it would begin to reduce drastically, by 2040, its impact on our security calculus will be almost nil due to obsolescence. After 2040, only some MKIs, S-400s and T-90s will need upgrades. Everything else will have been replaced.
