US Points to Dissent in Iran in Wake of Deadly Drone Strike Associated Press WASHINGTON - U.S. Defense Secretary Mark Esper and other administration officials joined President Donald Trump in trying to draw attention to dissent in Iran instead of lingering questions about the scale of the threat used to justify a drone strike on Iran's top military leader. Esper added to the uncertainty over the intelligence behind this month's killing of Gen. Qassem Soleimani when he said Sunday that he had seen no hard evidence that four American embassies had been under possible threat. Trump said last Friday that Soleimani had been planning such an attack. In appearances on Sunday news shows, both Esper and national security adviser Robert O'Brien said they agreed that Iran might have hit more than just the U.S. Embassy in the Iraqi capital. "It is certainly consistent with the intelligence to assume that they would have hit embassies in at least four countries," O'Brien said. But Esper, when asked whether there was a specific piece of evidence, replied: "I didn't see one with regard to four embassies." And in response to a question about whether Trump was "embellishing" the threat, Esper said, "I don't believe so." In a tweet both defiant and dismissive, Trump turned his attention again to supporting Iranian protesters and warning the Iranian government not to attack them or to pursue nuclear weapons. He tweeted: "National Security Adviser suggested today that sanctions & protests have Iran 'choked off', will force them to negotiate. Actually, I couldn't care less if they negotiate. Will be totally up to them but, no nuclear weapons and 'don't kill your protesters.' O'Brien had suggested the United States sees this moment as an opportunity to further intensify pressure on Iran's leaders, with whom the U.S. has been at odds for four decades. Iran's leaders already are under enormous strain from economic sanctions that have virtually strangled Iran's main source of income -- oil exports. Esper said street protests in Tehran show the Iranian people are hungry for a more accountable government after leaders denied, then admitted shooting down a Ukrainian passenger plane. "You can see the Iranian people are standing up and asserting their rights, their aspirations for a better government -- a different regime," Esper said. Watch related video by Henry Ridgwell:
