Well, he has a point. IIRC, though, Biden released the arms money (after the prosecutor trailing Hunter was fired).
He hasn't released the funds/arms here, and is holding up the transfer of east bloc jets to Ukraine from Poland.
Maybe they haven't pledged his cut.
Maybe Putin has.
But I agree,, we only 'know' that Russia invaded.
That's enough, really. That dirt isn't theirs, and they have no more right to stand on it than a Haitian does who swarmed across the Rio Grande has to stand on ours. Only the Russians came armed and spoiling for a fight, and that means Ukrainians will fight back.
We should so jealously guard our borders.
