My father taught me that you have to stand by your principles.

The Germans should be the first to sympathize with us [Egyptians]. They know how difficult it is to build a democracy following a dictatorship, and they were the first to be critical of Morsi's anti-democratic policies.

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.

If the world does not change course, we risk self-destruction.

As long as some of us choose to rely on nuclear weapons, we continue to risk that these same weapons will become increasingly attractive to others.

If I could have just 1 per cent of the money spent on global armaments, no one in this world would go to bed hungry.

I am an Egyptian Muslim, educated in Cairo and New York, and now living in Vienna. My wife and I have spent half our lives in the North, half in the South. And we have experienced first hand the unique nature of the human family and the common values we all share.
