Full Idea
You are waging war? You fear your neighbour? So remove the border markers: then you will have no more neighbours. But you want war: and that's why you set up the border markers in the first place.
Gist of Idea
If you don't want war, remove your borders; but you set up borders because you want war

A Reaction
The only reason to demarcate some territory is to keep other people out of it, which is a first act of gentle hostility. The European Union is trying to gradually dismantle the borders. Nietzsche had a creepy liking for war.
