Baron's fabrication of what Biden said shows that he (BVZ) is the only liar in this thread...

...here is JB's actual quote clarifying his position (Jan. 20, 2022)...something that Baron failed to investigate...(from NPR)
---------------------
"If any — any — assembled Russian units move across the Ukrainian border, that is an invasion," Biden said, adding that it would result in a "severe and coordinated economic response" that he has discussed with allies.

"Let there be no doubt at all that if [Russian President Vladimir] Putin makes this choice, Russia will pay a heavy price," the president said. But he also said the United States needed to be prepared for other scenarios beyond overt military tactics, such as paramilitary operations or cyber attacks.
--------------------

That is anything but a "Welcome Mat" to Putin

Note also, that the Biden administration supplied and trained Ukrainians on the use of critical Anti-Tank Javelin missiles during the prior year...missiles that kept Putin from seizing Kiev.

For whatever reason, Baron can't be trusted to post anything resembling the truth.
