Uh. No. Russia has modernized nearly all its nuclear arsenal. This includes missiles like the Topol-M and R-29RMU2. Let alone newer missile systems like the Yars or Bulava. Or air delivered weapons like the Kinzhal. You saw them use air launched stealth cruise missiles in the conflict in Ukraine i.e. the Kh-101. They also have what is essentially new weapon systems like the Avangard hypersonic glide vehicle in service. With others like RS-28 Sarmat and Poseidon due to enter service in the next 2-3 years. Heck this very year they basically finished tests of the Zircon which is an hypersonic cruise missile which can optionally use a nuclear warhead.
I find it quite perplexing that, while Russia first adopted, then rejected, the Brigade as the primary infantry formation (as the majority of the larger militaries have), that they would, then, go one step further in formation minimization, and move down to the battalion, and a small battalion, at that!
The Pentagon has been fairly circumspect and quite realist with regards to its comments and analysis of the war. It has left the cheerleading to the White House, the State Department, a number of other agencies, and also the Fourth Estate...
The first thing American apologists always fall back to is “moral-equivalence”, claiming that their war-crimes are more justifiable than others’!
But will China be able to save itself once NATO is finished with destroying Russia? I'm sure China has a better chance of winning its struggle against NATO with Russia still around, trying to appease the west wouldn't change their intentions to destroy China.
