Quote - General Rupert Smith

I was reading along in 'The Utility of Force' and came across this quote about the legitimacy of using force.
I reflected deeply on the matter and finally decided that it was legitimate simply on the moral grounds that if I, a strong, fit man, was walking down a road and saw and heard in a house evidence that a violent crime was in progress it would be my duty to break in and stop it, using sufficient force to do so.
He was talking about bombing Serbia/Serbian Forces to get a withdrawal from Kosovo.

Not really sure where I was going with that. Just wanted to remember it.
