""The only thing that matters when I'm talking about Iran, they can't have a nuclear weapon. I don't think about Americans' financial situation, I don't think about anybody. I think about one thing — we cannot let Iran have a nuclear weapon, that's all. The most important thing by far, including whether our stock market, which by the way is at an all-time high, but including whether our stock market goes up or down a little bit, the most important thing by far is Iran cannot have a nuclear weapon.""
