U.S. companies earn more from their investments in the EU than in the rest of the world combined.

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.

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.

David Cameron says he wants to keep Britain in the EU, but his tactics are so divisive that, if he gets what he wants it will be at the price of huge ill-will in Europe; or if he doesn't, it will be at the price of increased anti-EU sentiment in his own party and in British society.

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

States can be deterred by the fear of retaliation; non-state organisations cannot by deterred at all.

That's where my job comes in. Getting the E.U. and U.S. to agree.
