"The EU was primarily funded as a way to prevent Europe from being destroyed by inner conflicts again, which makes some sense after two devastating world wars that left Europe in ruins and killed millions of citizens. It's sad that this is sometimes forgotten and only emphasized by older politicians."

This is such an important point.

Whatever problems the EU indeed might have, its role in keeping the peace in a continent that has seen war almost uninterruptedly over the course of its history cannot be emphasized enough.

It is human nature blaming others for our own problems: as soon you cannot blame the EU anymore, you will start blaming your neighbors...
