Biden is Putin's best buddy.
It wouldn't surprise me in the least if in the future we learn that Biden had given Putin the nod and wink to invade the Ukraine while telling President Zelenskiy that the US would support him militarily.
You are clearly ignorant of the fact that when Biden calls Putin both sides are recording the call and there's 25-30 people listening in and taking notes on Biden's side- including Republicans. If Biden ever made any such offer, we would know of it pretty quickly. Only Trump ever tried to suppress a phone call to a head of state and in spite of all his threats and a full court press by his lawyers that call was leaked within hours, lead to a massive wave of resignations particularly within the Ukrainian diplomacy team and correctly lead to Trump's swift impeachment.
