The US and Israel struck targets across Iran, with President Donald Trump urging Iranians to overthrow the government in a conflict that is already spiraling across the oil-rich Middle East.

Yacoubian and Bloomberg Opinion Columnist Marc Champion discuss the conflict with Bloomberg's David Gura and Christina Ruffini.
