body: More broadly... what conditions must exist for a governmental body to enforce its laws on a foreign company?
  
  
  Concrete example: the European Union fined Google for what it found to be anticompetitive practices. What gives the EU power to enforce such a penalty on a US company?
  
  
  What if Google had no physical presence in Europe but did effectively serve and make money from Europe. 
  
  
  I assume France could not successfully sue and enforce against John Doe Individual in the US for selling Nazi paraphernalia online on a site accessible by people in France. Where is the line?
