RUSSIA'S ATTACK ON A CENTRAL UKRAINIAN CITY WITH AN EXPERIMENTAL, HYPERSONIC BALLISTIC MISSILE HAS ESCALATED THE NEARLY 33-MONTH-OLD WAR -- JUST AS THE UNITED STATES PREPARES FOR A TRANSFER OF PRESIDENTIAL POWER. N A STARK WARNING TO THE WEST, PRESIDENT VLADIMIR PUTIN SAID THE ATTACK WAS IN RETALIATION FOR UKRAINE'S USE OF LONGER-RANGE MISSILES FROM THE U.S. AND BRITAIN. AND HE'S VOWED TO KEEP TESTING THE NEW WEAPON. PRESIDENT-ELECT DONALD TRUMP REPEATEDLY SLAMS THE BIDEN ADMINISTRATION FOR GIVING KYIV BILLIONS OF DOLLARS IN AID. TRUMP HAS MOSTLY DUCKED QUESTIONS ABOUT WHETHER HE WANTS U.S. ALLY UKRAINE TO WIN.
