It's a little far fetched but Do you think that a army of clone would be better? If you took first class marines or soldiers of the French Foreign Legion and cloned them then wars might be easier to handle.
How is it gross? A. they wouldn't have a family so it wouldn't be as much of a deal if one died b. We can mess with the DNA and make super soldiers c. We can clone the best soldiers in the world, like the SEALS or something. d. Their entire life would be devoted into the military, so they wouldn't know anything else
