In modern Germany really no one wants to change frontiers, there are far more supporters for a smaller Germany or two Germanys, whatever you like. The reunification was costly and everyone regarded himself as a victim. In Western Germany we had to pay and the infrastructure now is often older compared to the East and in Eastern Germany they had even more problems and a complete change of almost everything. Germany today consists of 16 federal states and the only addition which would be accepted by the majority of people would be Mallorca. This is a joke for sure, Mallorca is the most popular holiday location for Germans.
