President Donald Trump declared Wednesday that Iran’s nuclear program must be destroyed, either as part of a new agreement with the U.S., or as the result of American strikes.

The president made the comments during a telephone interview with conservative radio host Hugh Hewitt, who asked Trump whether the administration has issued an ultimatum to Iran, demanding Tehran either surrender its uranium stockpile and centrifuges or “get bombed.”

“It is that simple,” said Trump in response. “It’s very simple. And I’d much rather make a deal, a really verified deal with total verification.”
