President Donald Trump said that Iran is "eager" to make a deal and revealed that the U.S. "blew up their three big bridges last night," in an interview with TIME Magazine Thursday.
"Why wouldn't they call? We just blew up their three big bridges last night," the President said. "They're getting decimated. They say Trump is not negotiating with Iran. I mean, it's sort of an easy negotiation."
When pressed about whether Israel would stop when the U.S. stops the war, Trump said that they will "stop when [he stops]," but added that they would stop unless "they're provoked."
"They'll do what I tell them. They've been a good team player. They'll stop when I stop. They'll stop unless they're provoked, in which case, they'll have no choice, but they'll stop when I stop," Trump said about the Israelis, according to Time.
Iran claimed its IRGC Nacy Command targeted the data centers of two major American companies in the region -- Oracle in Dubai and Amazon in Bahrain -- according to Iran's semiofficial Fars News Agency.
President Donald Trump shared a 10-second video that he says shows the "biggest bridge in Iran" coming "tumbling down, never to be used again," in a social media post.
"IT IS TIME FOR IRAN TO MAKE A DEAL BEFORE IT IS TOO LATE, AND THERE IS NOTHING LEFT OF WHAT STILL COULD BECOME A GREAT COUNTRY!" Trump added in the post.
