"Greece is", "Germany is:: It's logically faulty to treat a whole country as if it's a person.
Other logically faulty syllogisms: "Greeks are X", "Germans are Y".
One can say "some Greeks are X" or "some Germans are Y" or even "Many Greeks are" or "most Germans are Y" BUT a syllogism saying "(all) Greeks are X" or "(all) Germans are Y" is by nature faulty reasoning.
One can say that "Greeks (Germans or Brits or ..) tend to".
Greek are, Germans are, Greece is, Germany is, even for the economy of words, is FAULTY reasoning! but a syllogism that has more chances of non being faulty is eg: "Greeks tend to X (or be Y) more than Germans"
