Thank god the US military isn't competent then.
Again, the concept that "war is hell" doesn't seem to hit home for some people.
This is very murky territory no matter how you swing it
That dam generates a lot of electricity. In war, power plants are strategic targets. It would be an obvious potential target to weaken the Iraqi military and war machine.
So, the U.S. military studies the potential effects of destroying the dam. In the end, it does not destroy the dam.
Fast forward a few years, and people like you are condemning the U.S. military for...what? Figuring out that doing so would have resulted in many deaths, and not doing so?
You're saying that they shouldn't have even studied the issue? What if the enemy starts using it as a base of operations because they don't think it will be attacked? Like people have said, war is hell, it's unpredictable. Something unexpected could happen, something undesirable could become necessary. Without having information like this already available, sound strategic decisions can't be made. Then people like you would be complaining that they acted rashly without studying the issue first.
If you're saying that the very act of studying the issue is wrong, that's simply thoughtcrime, as well as incredibly naive.
And--perhaps ironically, from your point of view--the data and conclusions from the military study of the dam probably lends weight to the urgency of repairing it, thereby actually contributing to saving lives.
You've also neglected to consider that the dam could be attacked by anyone, including terrorists, competing regional forces, and (perhaps in Desert Storm) the Iraqis themselves. Imagine if Saddam Hussein had threatened to destroy the dam and kill millions of people unless the invading armies left.
Without knowing what would happen, it would not be possible to make a sound strategic decision, prepare for relief and evacuation, etc. It's better for everyone to know what would happen if the dam were attacked.
What you're advocating is naive ignorance.
Killing such a number of people in such a short time has been absolutely impractical until the last century. Only China, Japan, Russia, and the United States have been able to carry out such destruction and none have been able to do so in such a short period of time except for nuclear weapons in WWII.
People seem to act as if it means that you can call something "war" and suspend all ethics. Maybe if I feel like punching someone in the face, I could say "Hey man, getting punched in the face is hell. What are you gonna do?"
Maybe that's the blasé part of it that you were referring to.
There are people in the Pentagon considering all kinds of crazy scenarios all the time, so that when crazy actually happens the leaders can make a quick decision based on a briefing book that took a while to put together. It sounds ominous in the press, but it's really innocuous.

The military considers a lot of things.
