Iran is threatening retaliation by blocking the Strait of Hormuz - the world's lifeline of oil from all Gulf countries, including Saudi Arabia, Kuwait and Iraq. The move has brought America's rivals and allies on the same page.
China and Turkey have condemned the decision; and India and Japan, major buyers of Iranian oil, are scrambling to meet the shortfall.

Presenter: Imran Khan | Guests: Adolfo Franco, Republican strategist & Former Adviser to President George W. Bush and Senator John McCain; Mohammad Marandi, Head of the North American Studies Graduate Program at the University of Tehran; Dan Wang, China Analyst, The Economist Intelligence Unit
