Here are a few simple propositions on the matter of air war.
First, the farther away you are from the ground, the clearer things are likely to look, the more god-like you are likely to feel, the less human those you attack are likely to be to you. How much more so, of course, if you, the "pilot," are actually sitting at a consol at an air base near Las Vegas, identifying a "suspect" thousands of miles away via video monitor, "following" that suspect into a house, and then letting loose a Hellfire missile from a Predator drone cruising somewhere over Iraq, Afghanistan, Somalia, or the tribal areas of Pakistan.
Second, however "precise" your weaponry, however "surgical" your strike, however impressive the grainy snuff-film images you can put on television, war from the air is, and will remain, a most imprecise and destructive form of battle.
Third, in human terms, distance does not enhance accuracy. The farther away you are from a target, the more likely it is that you will have to guess who or what it is, based on spotty, difficult to interpret, or bad information, or even outright misinformation; whatever the theoretical accuracy of your weaponry, you are far more likely to miscalculate, make mistakes, mistarget, or target the misbegotten from the air.
Fourth, if you are conducting war this way and you are doing so in heavily populated urban neighborhoods, as is now the case almost every day in Iraq, then civilians will predictably die "by mistake" almost every day: the child who happens to be on the street just beyond camera range; the "terrorist suspect" or "insurgent" who looks, at a distance, like he’s planting a roadside bomb, but is just scavenging; the neighbors who happen to be sitting down to dinner in the house next to the one you decide to hit.
Fifth, since World War II, air power has been the American way of war.
Sixth, since November 2001, the Bush administration has increasingly relied on air power in its Global War on Terror to "take out" the enemy, which has meant regular air strikes in cities and villages, and the no less regular, if largely unrecorded, deaths of civilians.
