Technically, because the Treaty of Tripoli in 1797 was signed by John Adams, President Adam’s act of cowardly capitulation is probably what lead to 9/11. But don’t tell Marco. He’s on a roll.
“No, he made a decision not to take out its leader, which I think ended up being there, the situation that happened with 9/11. And as this was a response to an attack, that the reason why 9/11 happened was because of George W. Bush,” Rubio said. “And my argument is, if you’re going to ascribe blame, don’t blame George W. Bush, blame a decision that was made years earlier, not to take out bin Laden when the opportunity presented itself.”
