Not military expansion, but a more insidious one: legal expansion.

The German government must come up with a new law regulating its secret services, after the country’s highest court [Federal Constitutional Court] ruled that the current practice of monitoring telecommunications of foreign citizens at will violates constitutionally-enshrined press freedoms and the privacy of communications.

And:

The key legal question was whether foreign nationals in other countries were covered by Germany’s constitution….

Why, yes, yes they are. Because German sovereignty reaches deep inside other nations’ borders, other nations’ legal and political jurisdictions, overrides those nations’ own sovereignty. Germany’s laws not only apply outside German borders, they apply inside other nations’ borders.

The Court’s judges’ hearts may have been in the right place, but this sets an ugly precedent regarding the allegedly inherent superiority of German sovereignty.
