First off, that's not a direct quote, it's splices of different parts of his statement. To present it as one continuous quote when it isn't is dishonest. Second, the two week timeline is for us to attack, it is not the timeline for them to get nuclear weapons. If you had read Rubio's interview in full, you would understand the logic of that claim. You can argue the claim is wrong, but you either don't understand or are misrepresenting what the claim is. Because it isn't that Iran was about to get nuclear weapons.
