In Canada, the U.S. and most of Europe it may be easy to take political stands, this is something for which you can be forced to pay with your life, or your freedom, in many other parts of the world, from Iran to Russia to Pakistan to China.
Iran has made vile comments, anti-Semitic comments, comments about the destruction of Israel. It is precisely for that reason that even before I became president, I said Iran could not have a nuclear weapon.
When I came into office, the world was divided. Iran was resurgent. Iran is at its weakest point, economically, strategically, militarily, then since - then in many years. And we are going to continue to keep the pressure on to make sure that they do not get a nuclear weapon. That's in America's national interest and that will be the case so long as I'm president.
The number of the opposition has certainly increased [in Iran]. There is more disgruntlement, but because there is no media, the voice of this opposition is not heard outside Iran.
Americans coming home, an Iran that has rolled back its nuclear program and accepted unprecedented monitoring of the program -these things are a reminder of what we can achieve when we lead with strength and with wisdom, with courage and resolve and patience. America can do and has done big things when we work together.
We've had 60 years of intellectual development in Iran. How can we have the same system? Even theories of secularism are constantly being revised and changed.
We [USA] don't have diplomatic leverage to eliminate every vestige of a peaceful nuclear program in Iran. What we do have the leverage to do is to make sure that they don't have a weapon.
I have spent six years in prison, the last six years. Even if I was outside the prison, how much actual space was there for an investigative journalist to do his work in Iran? But I know one thing for sure: That we, the Iranian people, are much more in line of danger than the West.
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.
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.
We still have sanctions on Iran for its violations of human rights, for its support of terrorism and for its ballistic missile program. And we will continue to enforce these sanctions vigorously. Iran's recent missile test, for example, was a violation of its international obligations.
