Proliferation of nuclear weapons to terrorist organisations is far more dangerous than proliferation of nuclear weapons to states, even states like North Korea.

It is not viable for one country to demand a right to increase and upgrade its nuclear weapons capabilities while asking others to eliminate theirs.

The European Union is the world's most successful invention for advancing peace.

Of course the EU and member states must work to ensure that people moving from one country to another understand their obligations and their rights in areas like health, road safety and further education.

The EU and the U.S. often work together to develop international standards. This is the case in fighting terrorism and transnational crime, advancing trade liberalization, and combating piracy and intellectual property violations.

U.S. companies rely on the European market for more than half of their global foreign profits.

The E.U. is more than just a trade organization or a common market; it is a guarantee of democracy, freedom, justice, and human rights. Nations cannot stay in the E.U. if they do not respect these guarantees.
