A man must first care for his own household before he can be of use to the state. But no matter how well he cares for his household, he is not a good citizen unless he also takes thought of the state. In the same way, a great nation must think of its own internal affairs; and yet it cannot substantiate its claim to be a great nation unless it also thinks of its position in the world at large.

Theodore Roosevelt (1858–1919) American politician, statesman, conservationist, writer, US President (1901–1909)
