The United States and South Korea have launched massive military drills on the Korean Peninsula, amid rising tensions between the U.S. and North Korea. More than 17,000 U.S. troops and 50,000 South Korean troops will participate in the military drills. Soldiers from Australia, Britain and Canada will also take part. The military drills come after President Trump threatened to attack North Korea with “fire and fury” and members of the Trump administration continue to make the case for a preemptive military strike against North Korea.
