 IN ADDITION TO SUPPORTING UKRAINE, PRESIDENT BIDEN HAS BEEN VERY, VERY FOCUSED ON TWO OTHER THINGS. ONE, MAKING SURE THAT WE'RE MEETING OUR NATO COMMITMENTS, AND HE'S ADDED AN ADDITIONAL 20,000 TROOPS TO THE CONTINENT OF EUROPE AS AN EXAMPLE OF THAT. BUT NUMBER TWO, TO MAKE SURE THAT THIS CONFLICT DOESN'T ESCALATE, DOESN'T START WORLD WAR III.
