U.S. President Donald Trump told Fox News on Friday that United States military has the capability to dismantle Iran’s critical infrastructure within 48 hours.

“I didn’t underestimate anything,” Trump said when asked about the country’s leadership and capabilities. “We could take out their bridges and electricity capacity in two days. Everything.”

During the interview, Trump discussed past attempts to negotiate with Tehran, stating that the two sides had previously approached the outline of an agreement. “We really had the confines of a deal,” Trump said. “No nuclear, they were going to give us the dust… and every time they’d make a deal, the next day it’s like we didn’t have that conversation.”

Trump said this sequence occurred about five times. “There’s something wrong with them. Actually, they’re crazy,” he said, adding, “and you know what? Because of that, they cannot have a nuclear weapon.”

When asked about the strategic options available to the current Iranian regime, Trump rejected the idea that they hold any real leverage. “They have no deck,” Trump said. “The only thing they have going is a fake press.”
