"I’ve been saying it for 15 years. Iran can never have a nuclear weapon. Never. I said it in interviews, I said it at the UN, I said it in the White House, I said it on the golf course. They do not get the bomb. Not while I’m around. When I was president, they were broke. They were quiet. They were scared. I had them in a chokehold. Then Biden comes in, opens the cash floodgates, and suddenly the centrifuges are spinning and the Ayatollah is dancing in the street. Total embarrassment. Total collapse. And let me tell you something, we love Israel. We live for Israel. They are our greatest ally, our shining light. I would crawl through glass, folks. I would gargle the slop right out of Netanyahu’s hand. You know it, I know it. Whatever they ask, we do. It’s time to make Israel great again. To the very last American. If Iran even thinks about breathing toward Israel, they’re finished. I don’t care what it takes, we will protect Israel until there’s nothing left of us. And look, God forbid the Mossad blackmail on me comes out. You know what I’m talking about. But it doesn’t matter. I’ll say whatever they want. I’ll do whatever they want. Because we’re going all the way for Israel. No nukes for Iran. No hesitation. No America left? Maybe. But Israel will stand tall. That’s a Trump promise."
