Your comment implies that working for military/intelligence is automatically immoral. Nothing could be further from the truth. Believing that freedom is "free" is highly delusional. This civilization that we have, and enjoy, almost entirely depends on having more, better, bigger guns than the "bad guys" (in fact, having more, better, bigger guns is the best way to ensure you don't have to use them).

What you do with the guns is a different issue, but there's clearly many nations worldwide that focus on defense but not offense (maybe not US, but probably Switzerland).
