It's easy. You draw a red line on the ground, right? Then you wait for a chicken to come along. When he arrives, he puts his beak right on the line and he's hypnotized! ↗
The United States, and the president's made this clear, does not want Iran to develop a nuclear weapon. That's a red line for us. And it's a red line obviously for the Israelis so we share a common goal here. ↗
Our bottom line, if you want to call it a red line, president's bottom line has been that Iran will not acquire a nuclear weapon and we will take no option off the table to ensure that it does not acquire a nuclear weapon, including the military option. ↗
