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.

International inspectors are on the ground and Iran is being subjected to the most comprehensive, intrusive inspection regime ever negotiated to monitor a nuclear program. Inspectors will monitor Iran's key nuclear facilities 24 hours a day, 365 days a year. For decades to come, inspectors will have access to Iran's entire nuclear supply chain. In other words, if Iran tries to cheat - if they try to find build a bomb covertly, we will catch them.

When it comes to preventing Iran from obtaining a nuclear weapon, I will take no options off the table. ... That includes all elements of American power: a political effort aimed at isolating Iran, a diplomatic effort to sustain our coalition and ensure that the Iranian program is monitored, an economic effort that imposes crippling sanctions and, yes, a military effort to be prepared for any contingency.

I think my most important advice is to understand what are the foundations of a healthy democracy and how we have to engage in citizenship continuously, not just when something upsets us; not just when there's an election or when an issue pops up for a few weeks. It's hard work.

I'm always suspicious of politics dividing people instead of bringing them together.

I am willing to work with anybody who wants to have a serious conversation about our fiscal future. We're not going to do this under the threat of blowing up the entire economy. I will not negotiate over Congress' responsibility to pay the bills that have already been racked up. I don't know how I can be more clear about this.

I have never had to travel more than thirty seconds from home to office, and it's because of that that I've been able to maintain, really a family life that has nurtured and sustained me during this time [of presidency].
