Wouldn't surprise me if Cheney had said it; was shooting his friend just such a love tap?
"Humanitarian bombing" is an interesting phrase:

An interesting oxymoron (would 'uninteresting oxymoron' itself be an oxymoron?)
To my mind, John Betjeman trumped everyone, back in 1937, with:
"Come friendly bombs and fall on Slough!
It isn't fit for humans now,
There isn't grass to graze a cow.
Swarm over, Death!"
