U.S., Germany near showdown over Ukraine's tanks

STORY: On Friday (January 10) both will convene dozens of allies to pledge weapons for Ukraine at the United States' Ramstein Air Base, a meeting billed as a chance to provide the arms to shift the war's momentum in 2023.

Billions of dollars worth of military aid is expected, and countries including Canada, the Netherlands and Sweden have already announced new packages of armored vehicles and air defenses. But the meeting's success could depend on whether it brings heavy tanks, which Kyiv says it needs to fend off Russian assaults and recapture occupied land.
