Can't pin it on the Russians if the Americans brought it upon themselves.
GMD in Eastern Europe was a bad idea and Obama knew it. It's been known for decades that anti-ballistic missile systems are just as dangerous to the doctrine as ICBMs, SLBMs and nuclear bombs themselves. The US knew exactly what they were doing when they proposed GMD, and they knew exactly what they were doing when they unilaterally pulled out of the ABM Treaty. Then they make a big deal about Russian development in new missiles like the Bulava, Yars and Sarmat? Bitch please.
The more you push Russia, the more and better nukes they build. They don't have money to divert to other branches of their armed forces.
But for the foreseeable future, Russia will find ways to get past any ABM systems that the US can build. It's a bit like the current deal with reactive armour on tanks; Israel pioneered the concept, but the Soviets and Russians have been solely reliant on ERA since the T-72A appeared on the scene in '79. NATO develops better HEAT rounds, Soviets develop "gill armor" then Kontakt-1 ERA to counter it. NATO turns to APFSDS, Russia develops Kontakt-5 ERA to counter it. NATO makes better rounds like the M829A3 to get through ERA, Russia develops Relikt to counter it. NATO develops M829E4 with the intention of killing Relikt-equipped T-90AMs, Russia comes out with a surprise announcement at the parade of 4th gen Malachit ERA on the T-14 Armata. It's endless.
Getting sick of this shit, really. I guess Russia just has a terrible time keeping secrets, or (more likely) wants to strike fear into its enemies' hearts. On the other hand, US weapons development doesn't reveal jack shit until it's formally revealed. There are no surprises here. The biggest surprise (and long-term mistake) was deploying GMD in Eastern Europe and THAAD in South Korea. There is no better way of saying "it's time to end amicable diplomatic relations".
