As time goes on, you’ll probably think more about who “we” are and what cleaning up the mess may entail.
Young people are idealistic, and that’s probably a good thing. They may help us reconsider some of our preconceptions. But we (as a society, anyway) have to get practical at some point. At least for the foreseeable future, we have to have soldiers, and I personally think it’s better if neither we nor they conceptualize them as hired killers.
