As far as innocent casualities of war... we have to agree on what is acceptable.

If a terrorist is in a house with one civilian, is it acceptable to bomb the house and kill them both? That's an easy yes. How about Bin Laden is there with 10 Innocents.. I would think again an easy yes. 50? 100? What is acceptable, that's where many people disagree. You have some people that think there should be zero civilians killed, that is unreasonable.
