Here's Bush four years ago:
Today, America speaks anew to the peoples of the world:
All who live in tyranny and hopelessness can know: The United States will not ignore your oppression, or excuse your oppressors. When you stand for your liberty, we will stand with you.
And here's Obama today:
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.
It's an interesting contrast.
