"We have a historic opportunity to prevent..." - Quote by Barack Obama

“We want to see the Iranians engage, and as you know, we have attempted to bring about that engagement over the course of the last three-plus years. It has not proven effective.”

“A lot of the issues that I see, it is not an either-or situation.”

“We've been able to build up the Afghan security forces and stabilize it.”

“What if free people could live secure in the knowledge that their security did not rest upon the threat of instant U.S. retaliation to deter a Soviet attack, that we could intercept and destroy strategic ballistic missiles before they reached our own soil or that of our allies?”

“For the eight years I was president I never let my dream of a nuclear-free world fade from my mind.”

“A world without nuclear weapons would be less stable and more dangerous for all of us.”

“Several Americans, unjustly detained by Iran, are finally coming home. In some cases, these Americans faced years of continued detention, and I've met with some of their families. I've seen their anguish, how they ache for their sons and husbands. I gave these families my word. I made a vow that we would do everything in our power to win the release of their loved ones, and we have been tireless.”

“We've said to the Iranians all along . . . we still remain open to diplomacy. But it's been very clear that the Iranians don't want to engage with us.”

“The Iranians have shot down drones. They tried to destroy the Saudi oil fields. They tried to storm our embassy. So, when my Democratic friends say we need appeasement, well appeasement hasn't worked. And I think that we've learned, with respect to Iran, that weakness invites the wolves.”
