"Every morning, I received a briefing on the threats to our Nation. And I vowed to do everything in my power to keep us safe."
I think those are the best lines from President Bush's farewell speech.
You can see that I've placed the "retirement" tag on this post. While he can't really "retire" from the presidency - not being elected again isn't the same thing as retiring - it is safe to say that Bush is "retiring" from public life.
