CNNs Anderson Cooper asked Trump, "If you're concerned about proliferation, letting other countries get nuclear weapons, isn't that proliferation?"
As part of a winding response, Trump said that he both opposes nuclear proliferation ("No, no, not proliferation. I hate nuclear more than any;" "I don't want more nuclear weapons" and supports some countries obtaining nuclear weapons for the first time.
"Wouldn't you rather in a certain sense have Japan have nuclear weapons when North Korea has nuclear weapons?" he asked Cooper.
Cooper also asked Trump: "Saudi Arabia, nuclear weapons?"
Trump: "Saudi Arabia, absolutely."
Cooper: "You would be fine with them having nuclear weapons?"
Trump: "No, not nuclear weapons, but they have to protect themselves, or they have to pay us.
