Saddam's execution video

Where does it state that we are the worlds cop and as such, need to police everyone else's actions?

If history is a guide, the right policy and the best policy for a free country was enunciated by Thomas Jefferson in his First Inaugural Address over two hundred years ago:

"Peace, commerce, and honest friendship with all nations -- entangling alliances with none."

it's the un's job to be the world's police.
we are a part of that organization. just because other corrupt countries prefer to work on the contrary to what it was intended for does not negate other member countries responsibility.
