NORAH O'DONNELL: So why do we need to test our nuclear weapons?
US PRESIDENT TRUMP: Well, because you have to see how they work, you know. You do have to, and the reason I'm saying testing is because Russia announced that they're gonna be doing a test. If you noticed, North Korea is testing constantly, other countries are testing. We're the only country that doesn't test, and I don't wanna be the only country that doesn't test.
NORAH O'DONNELL: Are you saying that after more than 30 years, the United States is going to start detonating nuclear weapons?
US PRESIDENT TRUMP: I'm saying that we're going to test nuclear weapons like other countries do, yes.
NORAH O'DONNELL: But the only country that is testing nuclear weapons is North Korea. China and Russia are not...
US PRESIDENT TRUMP: No, no. Russia is testing nuclear weapons. And China is testing them too. You just don't know about it.
NORAH O'DONNELL: That would be certainly newsworthy. My understanding is that what Russia did recently was test essentially the delivery system for nuclear weapons. Essentially - missiles. Which we can do that, but not with nuclear warheads.
US PRESIDENT TRUMP: Russia is testing and China is testing, but they don't talk about it, you know. We're an open society, we're different. We talk about it, we have to talk about it. Because otherwise you people gonna report. They don't have reporters that gonna be writing about it, we do.
