And while the biggest arms dealer in the world is your boss - the President of the United States, who ships more merchandise in a day than I do in a year - sometimes it's embarrassing to have his fingerprints on the guns. Sometimes he needs a freelancer like me to supply forces he can't be seen supplying. So. You call me evil, but unfortunately for you, I'm a necessary evil.
And don't forget who funds the R&D and why - "war is the most profitable business on earth".
