Actually it's a figure of speech, sometimes referred to as multiplicity inferences.
Had I said the EU has "more than one" corrupt vice president then I would accept your point. However, saying the EU has corrupt vice presidents is ambiguous as to the number. To me, it implies at least one but possibly more than one.
It's very pedantic from you again though. If you went on holiday and said your daughter fed dolphins, I wouldn't be hugely upset if it turned out that she only actually fed one dolphin. "How dare you lie to me, you should have said she fed one dolphin only". ????
Like I said, if that's the best you've got then you must be pretty desperate.
