A few pros are the fact that cloning could revolutionize the way the world works. Most hospitals would be able to save many lives with the new ability to clone organs. The military would never run out of troops to send out to fight for our country. Economics wouldn't be the same after cloning.
Some cons to cloning are if there was a disease in something someone cloned that disease would spread. If an enemy of the U.S got control of the cloning machine then the cloning troops would be backfired and would work against us. Economics could be improved or completely destroyed.
