Trump on Friday told a rally for candidates in South Florida that U.S. warships returning from the Middle East could stop over in Cuba on their way back from the Iran war, his latest suggestion of taking an interventionist approach to the nearby country. “We’ll do a little stopover,” Trump said, reported Fortune. “Actually, what we’re going to do with Cuba is, we’re going to come back from Iran. Those beautiful ships will pass Cuba. We’ll have one of them stop about 50 yards off the coast. They’ll raise up their hands. And then we’re going to send [Secretary of State] Marco Rubio in to finish up the deal.”

Rubio told reporters separately that Cuba has been a national security threat for years because of its ties to U.S. adversaries and that Trump is intent on addressing it. While saying the Trump administration wants to resolve differences with Cuba peacefully, Rubio voiced doubts that the U.S. could reach a diplomatic resolution with the island’s current government.
