Pro EU so they make stupid claims. Like peace in Europe. The fact that we still have Russia posing a threat to Europe isn't mentioned. Economic stability can be easier achieved with a simple trade agreement. The Fall of the Berlin Wall has nothing to do with the EU. Europe without frontiers is a two sides coin. The lack of borders is creating a crisis with illegal immigrants.
But this article high lights the EUs growth and it continues to grow. The sooner it's brought down and replaced with a trading deal the better.
