What's the likelihood we will see the war with Iran break out again?

A new report from CNN says President Trump is now more likely to start military action against Iran again as he grows frustrated with Tehran for not taking the peace deal he offered. It comes after the President said the ceasefire is on "life support." Meanwhile, the speaker of Iran's parliament said his country's military stood ready to "teach a lesson" to any aggressor. Will we see the war break out again, or is this tough talk to pressure the other side to make a deal? University of Maryland Professor Josh Shifrinson talks about it with L.A.'s Morning News.
