There is some context to his statement. Economically Russia is on the ropes, additional sanctions (which I support), could be the tipping point. While their military is viewed as a peer adversary, Russia's economy is far less impressive. Their GDP is 11th on the world list, coming in well below Italy, Canada and Brazil. The have taken massive losses and are unable to rebuild some key capabilities like the bombers that were lost in Operation Spider Web.
This week Putin officially acknowledge the economic difficulties, some thing he never does but in this case he has no choice. The offensive expected in the summer of 2026 is likely their last gasp at victory in Ukraine.
I understand and respect your opinion, I just think at a much higher strategic level Russia has been removed from the table as a major peer threat to the United States. Their military humbled and destroyed, likely 1 million casualties with as many as 250,000 soldiers killed, it will take them a generation to recover and we didn't lose a single American soldier.
