Iran, US tensions set region on edge

After a brief easing of tensions, relations between the United States and Iran remain strained, with the prospect of potential U.S. strikes weighing heavily, as the Pentagon announced on January 15 that it was redeploying an aircraft carrier strike group -comprising fighter jets, guided-missile destroyers and at least one attack submarine - from the South China Sea toward the Middle East, with reports indicating the force was expected to arrive within about a week, according to Gabrielle Nadler.
