The absolute low point for me in more than 30 years of professional life was the Brexit vote.

For all its shortcomings, European co-operation and integration has created an understanding of shared destiny. We no longer point guns at each other; we fight it out at a conference table. And we will continue to do so when the U.K. is no longer a member state but, I hope, still a friend.

The issue of migration has played a key role in all of our member states, wherever we are. Only we, as a European Union, can convince our citizens that we do have an answer to this - not deny migration, not pretend you can solve it by building fences and walls, not pretending we can solve it by letting everybody in.

Whether they are Jewish, Muslim, Christian, or atheist, everybody has a place in this society.

There is a need for more effective dialogue... between the government and the international community.

My mom is like this hard-core, liberal feminist. She's a professor in Boston, and she's been teaching women's studies for 30 years and international politics.

The federal government has sponsored research that has produced a tomato that is perfect in every respect, except that you can't eat it. We should make every effort to make sure this disease, often referred to as 'progress', doesn't spread.

Politics is the art of achieving political goals - of achieving what is possible in a given situation - that is, in a situation that has its conditions and its limits.
