After the Berlin Wall came down I visited that city and I will never forget it. The abandoned checkpoints. The sense of excitement about the future. The knowledge that a great continent was coming together. Healing those wounds of our history is the central story of the European Union.
Socialism is the gradual and less violent form of communism, and socialist is the project of the European Union, which was born in Maastricht in 1992. The intent was to save socialism in Europe after the fall of the Berlin Wall and the predictable bankruptcy of the welfare state in the West as well.

The European Union is the world's most successful invention for advancing peace.
It is not acceptable that European Union countries are divided into those who give and those who take.
If the euro zone doesn't come up with a comprehensive vision of its own future, you'll have a whole range of nationalist, xenophobic and extreme movements increasing across the European Union. And, frankly, questions about the British debate on EU membership will just be a small sideshow compared to the rise of political populism.

Albania, Macedonia and Greece have managed to create a good partnership in the south of the Continent and are making progress in blocking the spread of the conflict. But any spillover could destroy this European-oriented partnership and create problems for the European Union countries themselves.
