Donald Trump believes that the world will be safer if more nations have nuclear weapons. And he's said Saudi Arabia should get them, Japan should get them, Korea should get them. And when he was confronted with this, and told, wait a minute, terrorists could get those, proliferation could lead to nuclear war, here's what Donald Trump said, and I quote: "Go ahead, folks, enjoy yourselves."
Senate has to advise and consent. That doesn't mean you have to vote yes; you can vote no. It's not a rubber stamp. But what these guys are doing is, "Wait a minute, we don't have to vote yes or no, and maybe we can trick our voters into not holding us accountable for not voting yes or no."
