You’re coddling a nuclear power by claiming it’s entirely subject to evil us pressures. They could have implemented a no first use policy any time in the past 20 years just fine, but they haven’t.
I’m dismissing you because your points are wildly silly and blatantly have an agenda to paint Russia as a victim of external forces. Russia is a big boy country, they can implement a simple policy.
Don’t worry, the us could too.
PS, every single country in the world is responding to external and internal pressures.
