The Iranian military figure responsible for targeting and killing thousands of people, including hundreds of U.S. troops, was killed in a drone strike in Iraq early Friday morning, along with several other key figures connected with Iranian-sponsored terrorism in the Middle East.

But the killing of Qassem Soleimani is sparking fierce debate.  President Trump says he acted to stop a war while his critics claim he's on the brink of starting one.  They also argue Trump should have sought congressional approval or at least consulted with Democratic leaders before commencing the strike.  And are we on the verge of a full-scale war with Iran?

Retired U.S. Navy Capt. Chuck Nash studies Iran closely.  In this conversation with Greg Corombos, Nash explains why he believes the attack on Soleimani and his associates was fully warranted, whether Trump had an obligation to inform Congress of the attack, the dilemma now facing Iranian leaders, and how a regime change inside Iran must happen from within.
