Kofi's Parting Shot.

"As [Harry] Truman said, 'We must, once and for all, prove by our acts conclusively that right has might.'

When it appears to abandon its own ideas and objectives, its friends abroad are naturally troubled and confused." As Kofi Annan bids farewell to his post at the UN, he offers some words of wisdom to America -- and to Dubya -- on our nation's role in the world.
