Obama’s inaugural address had a sprinkling of foreign policy realism:
[Earlier generations] knew that our power grows through its prudent use; our security emanates from the justness of our cause, the force of our example, the tempering qualities of humility and restraint.
Unfortunately, that sentence came just after this:
And so to all other peoples and governments who are watching today, from the grandest capitals to the small village where my father was born: know that America is a friend of each nation and every man, woman, and child who seeks a future of peace and dignity, and that we are ready to lead once more.
A nation tempered by humility and restraint would not presume to lead every person in the world.
