Joe Biden Asked if He Was Too Quick to Rule Out Military Intervention

Biden said that the most important thing is for the United States and its allies to stay united.

"The single most important thing is for us to stay unified and the world continue to focus on what a brute this guy is and all the innocent peoples' lives are being lost and ruined and what's going on. That's the important thing," Biden told reporters.

"But look, if you're Putin and you think that Europe is going to crack in a month or six weeks or two months, why not - they can take anything for another month. But we have to demonstrate," he said. "The reason I asked for the meeting, we have to stay fully, totally, thoroughly united."
