White House National Security Adviser Michael Flynn issued a warning to Iran this afternoon, saying the administration is "officially putting Iran on notice" after Sunday's ballistic missile test.

Rep. Ron DeSantis (R-FL) said on "Your World" today that Iran is back to "saber-rattling," which they were allowed to get away with for the past eight years by the Obama administration.

He said that Flynn's statement was important because it lets Tehran know that they can't get away with this "belligerent behavior."

DeSantis said we can expect the Trump administration to be tougher on Iran, and our Gulf allies will be very happy to see that.

"What does it mean to be 'on notice'? I'm not sure. But I think, at a minimum, I think the Trump administration has got to be open to tougher sanctions against Iran," DeSantis said. "I think you're going to see a much stronger stance toward Iran."

"And I think a stronger stance will end up putting Iran back in the box that they belong in."
