This idea is a horror for many Germans and Europeans: a wall?

After all, their country, their continent was once divided by a terrible border.

The Saxon Prime Minister Kretschmer, who grew up behind the same wall as Angela Merkel, has now said: "We need fences and we probably also need walls".

It's about the European external border.

In fact, freedom is only preserved in the European Union if the union of states controls its external borders.

This is not a solution to the refugee problem.

But doing nothing would positively encourage the potentates in Moscow and Minsk.

to continue their unworthy game with the lives of refugees.

The connections to Belarus must be cut.

Until things get better, the affected states on the European eastern flank must be supported - with help for refugees and with securing the border.

Hopefully you will notice again in Warsaw that no country is an island and that Poland needs the EU in this area too.

Germany has also learned that the refugee crisis in Bavaria, for example, or now in Brandenburg or Saxony, is very different from that in Lower Saxony or Berlin.

A border fence can not only separate, but also protect.

But everyone has to work on this.
