I still believe that any country understands that if they use nuclear weapons, they will be wiped out of existence. They could be irrational in many ways, but I don't think they're irrational to the point that they're ready to annihilate their own country.

Once in a while, I have to pinch myself to remind myself I am Nobel laureate, but that is not part of my work plan every day.

Nuclear proliferation is on the rise. Equipment, material and training were once largely inaccessible. Today, however, there is a sophisticated worldwide network that can deliver systems for producing material usable in weapons.

Egypt under Hosni Mubarak had deteriorated to the status of a failed state. We must wipe the slate clean and start again.

Egypt is indeed deeply divided. Without reconciliation we have no future. The Muslim Brotherhood is an important part of our society. I very much hope that it will participate in the next round of talks. I will be the first to protest if the imperative of fairness isn't adhered to.

Iran has the technology to produce the highly enriched uranium, which is not automatically meaning nuclear weapon.

Whether weapons exist in Iraq, Saddam Hussein or post-Saddam Hussein, it is a serious enough issue that require that we continue to go and make sure that Iraq does not have weapons.
