Obviously, here we have JFK with that incredibly simple and powerful formulation, "Ask not what your country can do for you; ask what you can do for your country," an incredibly noble sentiment.
Oczywiście mamy tu Johna Fitzgeralda Kennedy'ego z nader prostym i mocnym sformułowaniem, "Nie pytajcie, co kraj może zrobić dla was; pytajcie, co wy możecie zrobić dla kraju," niesamowicie szlachetne uczucie.
