Did the Benghazi Committee Learn Anything New from Petraeus? Gowdy Explains

Lt. Gen. Michael Flynn (Ret.) tore apart the Obama administration's foreign policy strategy in a sit-down with Megyn Kelly. 

Flynn, the head of the Defense Intelligence Agency from 2012 to 2014, first spoke out over the summer, saying the administration made a "willful decision" to allow ISIS to grow as part of the effort to oust the Assad regime in Syria.

In her opening, Megyn highlighted the rising tensions between Saudi Arabia and an emboldened Iran, the resurgence of the Taliban in Afghanistan and a chilling new video that shows an ISIS weapons lab in Syria.

"To hear [the White House] tell it, it's all rosy. American leadership has stopped it from being worse," she noted to Flynn. 

He responded that he sees the 2016 presidential election as "huge" because the next commander-in-chief will face an "absolute mess" in the Middle East that could potentially last for their entire presidency. 

"Whenever there's a void in U.S. leadership, it will be filled by dictators, terrorists," he explained, adding that he sees problems coming with immigration into Europe and Russia getting involved in the region. 

Flynn said a United Nations resolution or a "big speech" will not solve these problems. 

"I want to cheer for our country and our president, but I find it really difficult because I feel like we're playing on a strategic football field and we're not even in the stadium," said Flynn. 

He specifically pointed to last week's provocation by Iran in the Strait of Hormuz. Five Iranian Revolutionary Guard vessels approached the USS Harry S. Truman, and one of them fired missiles within 1,500 yards of the U.S. aircraft carrier.

Flynn said that was a "test" from Iran to see what the U.S. military would do in response. 

"It's looking at us and kind of giving us the big middle finger and saying, 'We're gonna see what you're gonna do about it. Are you gonna punch us in the nose?'" he explained
