President Donald Trump said Thursday, February 19, that Iran had at most 15 days to make a deal on concerns starting with its nuclear program, suggesting the United States would attack if it did not.

"We're either going to get a deal or it's going to be unfortunate for them," Trump told reporters on Air Force One. Asked about his timeline, Trump said, "I would think that would be enough time – 10, 15 days, pretty much maximum."

Trump earlier Thursday had suggested 10 days for Iran's clerical state to reach an agreement.

"It's proven to be over the years not easy to make a meaningful deal with Iran. We have to make a meaningful deal otherwise bad things happen," Trump told the inaugural meeting of the "Board of Peace," his initiative to secure stability in Gaza.
