The casualty rate is nowhere near the neighborhood of WW II. When the armies move so that entire populations have to flee on foot and this is happening around the world, then this will be war on that scale.
I was making a point online the othere day, and for historical perspective, I chose Iwo Jima.
We lost 6800 young men in 36 days. It just STAGGERS me to think of it, given how small Iwo Jima is.
Any death in war is terrible, but given the size of Iraq and Afghanistan, in historical terms, have done pretty well.
But I still wished we hadn't been attacked, and I wish we had those 3000+ on 9/11 and 2500+ killed in our military since then, back amongst the ranks of the living.
