US-Iran tensions: 1,500 troops to be sent to the Middle East

Correction: 7/9/2019: A previous version of this video introduction said Iran had withdrawn from a multinational nuclear deal, formally known as the JCPOA. That was incorrect, the United States has withdrawn.

 

Tensions have been rising since the United States pulled out of the nuclear deal.
