"war is as you know especially today is indescriminant..innocents die and are called collateral damage." Actually, war today, as waged by modern armies (excluding savages like the LRA in Uganda), is far less indiscriminate than it ever was in the past. Through history, war has rarely respected the concept of "non-combatants"; rape (literal as well as metaphorical), pillage, and plunder have been the typical standard of conduct for soldiers since before history began to be written. American armies go to great lengths, at sizable risks to themselves, to avoid civilian casualties. But the reality is that wars will happen; it only takes one armed side to have a war, and any country not prepared to defend itself is a sitting duck for those with fewer scruples.
The Sermon on the Mount is not a treatise on government. Governments have rights and responsibilities that individuals do not. Should we have no police force as well, and take the locks off our doors? Governments have a divine mandate (see Romans 13) to restrain evildoers, both internal and external, and sometimes deadly force is necessary. That doesn't mean "all's fair in love and war"; the Geneva Conventions, for instance, describe limits. But at the same time I don't believe it is fair to our military to expect them to mourn when they do their job right and accomplish their mission. And I don't think we should mourn, or even be indifferent, either. The SEALs did a truly remarkable job--and, by the way, there were no deaths of women, children, or people outside the compound.
