We can never afford to live in a world, or have our children inherit a planet, where such people have nuclear weapons with such actions," US Secretary of State Marco Rubio said Friday, warning against the Islamic Republic's pursuit of nuclear weapons. Referring to the oppression and killing of people in Iran, he added: "They massacred tens of thousands of their people in the streets. And then, when you're injured, they go to the hospitals and kill you on the hospital bed, and often kill the doctors and nurses who treated you." Rubio concluded: "This is what they do to their people. Imagine what they would do to us if they had nuclear weapons.
