Did you read the whole statement?
“weakened to the degree that it can’t do the kinds of things that it has done in invading Ukraine”
Only weakened to the degree it can’t invade its neighbours.
You should step back and think a bit. You are supporting a policy from the same people who botched the Afghanistan withdrawal, want to get us back into Syria and think Iran deserves nuclear weapons.
Besides, the only way to truly "weaken" a nuclear power is to completely take them over militarily so no group inside the nation can get control of those weapons.
If you think we can take Russia's military offensive capability away without occupying the nation, please enlighten us.
