If Germany wants yet again to create a dominion on the rest of the EU, then, yes, it is a good policy to remind them that they already tried and that the people living around their country might not agree with their natural superiority.

Germany got where it is now by pillaging the continent during the war, and that's a fact, and being perdonned afterwards, and that's another fact. So a little bit of consideration for the people around might be in order.
