I gave up lots of things I love doing: writing, and business, and playing the piano and so on.
I don't think my principles change. I think the way in which you apply those principles to modern society changes.
We have to face the reality of climate change. It is arguably the biggest threat we are facing today.
Unless there is meaningful change in Syria and an end to the crackdown, President Assad and those around him will find themselves isolated internationally and discredited within Syria.
People feel that the EU is a one-way process, a great machine that sucks up decision-making from national parliaments to the European level until everything is decided by the EU. That needs to change.

Let's not be afraid to speak the common sense truth: you can't have high standards without good discipline.
Very few conflicts in the history of the world have been satisfactorily concluded according to a published timetable, because you lose all flexibility in dealing with your opponents.
