The gravest threat faced by the world is of an extremist group getting hold of nuclear weapons or materials.

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.

Almost all of the liberal and Christian members of the constitutional commission have withdrawn, because we all fear that the Muslim Brotherhood will pass a document with Islamist undertones that marginalizes the rights of women and religious minorities. Who sits in this group? One person, who wants to ban music, because it's allegedly against Sharia law; another, who denies the Holocaust; another, who openly condemns democracy.

Democracy is not an instant coffee.

Nobody wants any country to have nuclear weapons.
