I think the journey for a politician goes from wanting to please all the people all the time, to a political leader that realises in the end his responsibility is to decide. And when he decides, he divides.

I think social media is a revolutionary phenomenon all in itself.

At the heart of my politics has always been the value of community, the belief that we are not merely individuals struggling in isolation from each other, but members of a community who depend on each other, who benefit from each other's help, who owe obligations to each other. From that everything stems: solidarity, social justice, equality, freedom.

People divide into groups where they talk to each other, but don't talk across the divide. And yet most of the challenges we face in the world today are challenges that are to do with trade, with technology, with how you make sure that people are properly educated, reform your health care system.

I think the single most important political distinction today is actually between open-minded versus closed-minded, and that's why I think this crosses the boundaries of traditional - center-right and center-left have much more in common with each other right now than the right does with the center-right, and the left does with the center-left.

There are those people who basically don't like those who are different. Now, that is a prejudice and it's a prejudice that's dangerous because in the world today, the world works through connectivity. It works through going across the boundaries, but faith and culture and race in a nation.

Our ultimate weapon is not our guns but our beliefs ... Ours are not Western values. They are the universal values of the human spirit and anywhere, any time, ordinary people are given the chance to choose, the choice is the same. Freedom not tyranny. Democracy not dictatorship. The rule of law not the rule of the secret police. The spread of freedom is the best security for the free. It is our last line of defence and our first line of attack.
