If the army was made up entirely of clones, the country would be more efficient.
This army would be born and raised outside society; all the clones would see would lie within the walls of the training camps.
No civilians would care what would happen to these clones; they wouldn't know them.
There would be no benefits to pay to widows of fallen soldiers.
People wouldn't care as much about where the soldiers were sent; they wouldn't care if they died or not. They wouldn't be as involved - many people have the misconception that clones are somehow sub-human.

I wonder if any governments will take advantage of this. Do you think it would work?
