The anti-Ukraine press is trying too hard to read into this what Biden did not say.
This was a fundraiser. He was trying to raise money. He often tries to make him self look tough by talking down about someone else. Zelensky was a convenient target. He also said he was telling European leaders "America is back" when they would know better. The speech built himself up at the expense of Zelensky and other European leaders, who definitely noticed it.
This speech was for show, not substance. There is no policy shift here.
Nice point pnhd,
