Well, I used to believe in the way you believe, coming from a military family, my Grandfather served in WW2 and the Korean War, Dad served in Nam, my brother served in Desert Storm, and I myself served in OIF and OEF. Wars are going to be different than what my parents and my grandfather went through.
I want to think today's war are clean and stand off, but that wouldn't mean anything, you would think you can just win a war firing a few missiles and dropping a few bombs? Well, I can tell you that if people are going to give up that easily, you won't be in a war to begin with.
I was with the US Army, I trained as a cavalryman, I rode a tank and APC to war, but do you know what the best army in the world on the first day of going to war with Iraq told me?
"Glad that you are here, but your armor is not, and we will be using you as an infantry"
Why can't we just win a war in Iraq by dropping a bomb? That's what I had been asking before I had my sorry ass dragged in line, giving me a rifle and telling me to do stuff that I had not done in 2 years before when I was trained as a Bradley Commander. And that is the US Army and we were fighting Iraq. Do you think yours can be better?
I can tell you the hardest part in war is not to kill people and be killed, that's the easy part, the hardest part of a war is to get a smoke when you want to, and take a crap when you had to. And there are no way you will know how hard is those things to be done unless you were in the thick of it.
