Again, you neglect deeper thought. Russia doesn't need nuclear bombers any longer. They have nuclear missiles and subs if they need nukes.
They also have the laser that is taking out drones and enemy aircraft. And Russia will only be strengthening them.
Russia won't be producing any such 'backwards' bombers as those that were destroyed. They are-building/have-built next generation bombers that are far in advance of those that were destroyed.
And with the strength of China and North Korea behind them, and the Israel-Iran war increasing oil prices, Russia is sitting in a stronger and stronger position all the time. Nobody can sanction Russia out of world economics.

So... we have here two people. One says that the bombers were destroyed, but are needed so they will be replaced and we have a BAdecker saying that they are not needed anyway. Interesting, two different stlyles to try to negate what happened.
Ruzzias nuclear deterrent is based in first and second strike capabilities. It requires, bombers, missiles and submarines. That is the Ruzzian doctrine.
This document states that Ruzzian military give top priority to nuclear deterrence and are developing "delivery methods". That is true. That these methods will ever reached daylight or an industrial scale... I doubt it very much.
