And the answer is perfectly simple. In Kosovo, you have, after the removal of the loss of its regime, you had a process of political and economic reconstruction that took its part without the intervention of terrorism. If you had the intervention of terrorism, by the way, it would have been extremely difficult there - but we didn't.

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.
