U.S., South Korea open to expanded military drills to deter North:

U.S. President Joe Biden and South Korean President Yoon Suk Yeol said after meeting Saturday that they will consider expanded joint military exercises to deter the nuclear threat from North Korea at a time when there's little hope of real diplomacy on the matter.

The announcement reflects a shift in direction by both leaders from their predecessors: Former U.S. President Donald Trump had considered scrapping the exercises and expressed affection for North Korean leader Kim Jong Un. And the last South Korean president, Moon Jae-in, remained committed to dialogue with Kim to the end of his term despite being repeatedly rebuffed by the North.

Biden said cooperation between the U.S. and South Korea shows "our readiness to take on all threats together."
