The correct response is the ever-increasing precision of bombs and rockets/missiles.
World War II: If you were bombing an area, you were lucky if your bombs hit within 1,000 yards of your target. On D-Day, Allied bombers were sent to bomb German troops and equipment in the rear that were ready to reinforce the defenders. Due to intermittent cloud cover, the bombs fell two miles behind their intended strike point/area. The result was “a lot of dead French cows” and property damage. Accuracy gradually improved but “thousand bomber” raids also occurred.
Korea: Due to a failure to secure their communications system properly, and better air reconnaissance by Allied aircraft, we pretty much knew where everybody was and their strength. By the time the Russians intervened and improved their communications security, we were doing well. The entry of the Chinese had General Douglas MacArthur suggesting the use of atomic bombs. When President Truman heard of this, he was relieved of command.
Then there was the issue of civilians fleeing to safer areas. As it happened, North Korean troops mixed in with the civilians. Due to a lack of sufficient Allied personnel to check who was who, there was at least one firefight where both enemy troops and civilians were killed. The war technically did not end. There is an armistice in place, that’s it.
Vietnam: Despite our strength of numbers, B-52 bombers, and helicopter gunships (which kept getting upgraded), the civilians were aiding the military. Someone, I don’t know who, ordered a nuclear bomb to be mounted on a fighter-bomber for a strike on Hanoi, the capital of North Vietnam. Again, this did not happen.
However, due to ongoing negotiations, politicians sometimes hindered US military forces. Bombers conducted “rolling thunder” raids to kill concentrations of the “enemy.” The definition of who was the enemy varied. Regular North Vietnamese Army troops wore uniforms, the Vietcong wore “black pajamas.” Civilian deaths were inevitable. The very sad truth is that a defoliant called Agent Orange was dropped on areas the enemy might use as cover, but that substance ended up in the drinking water the civilians used as well. Birth defects followed. A friend of mine who was out in the field told me an Agent Orange drop fell directly on their position.
Today. We have laser-guided bombs and missiles. We also have conversion kits to turn a regular bomb into one that can be controlled on the way down. Keep in mind, depending on the target, these bombs are dropped from around 5 miles altitude. We also have missiles with cameras mounted in the nose that can relay images until impact. Drones are stealthy and filled with optical and electronic equipment, and carry rockets. They can be sent on missions that - mostly - cause zero or minimal civilian deaths.
But we are in an era of Low-Intensity Conflict and the enemy does not wear uniforms in many cases. The Republican Guard in Iraq was decimated, but anyone pointing a weapon at Allied troops, even if dressed as a civilian, is the enemy. Fortunately, surveillance has increased in effectiveness greatly, which is good and bad. All civilian and military communications systems can be monitored, globally. The US military has boasted that we now have a “24 hour, global strike capability.” That kind of rapid response is quite new. What is involved exactly is unclear to me. I pray that everyone involved can go to bed each night knowing that he or she had no other choice to defend this country, and our Allies, by doing what they do.
