This is the military in a nutshell. It ostensibly needs to protect the nation, but civilian industries exist as a result, whose executives have generals in their pockets. If the industry no longer serves the needs of the military, then the military should stop using it; but that doesn’t reduce the plight of a worker who would become unemployed as a result. Who suffers from this tension? Every taxpayer who isn’t an executive or a general with a cushy retirement job, but especially workers and average servicemembers.
People want their answers to be simple. In this case, if you can say there’s a good side and a bad side in a conflict, you can pretend that verbally supporting the good side no matter what is good, moral praxis.
