I have been giving continuing thought on this idea of investing in defense stocks and Maybury's advocacy of same. I would quote something from Rothbard, as it captures well an aspect of my objection:
"This [the availability and use of modern weapons of war as opposed to guns or bows and arrows] is why the old cliché no longer holds that it is not the arms but the will to use them that is significant in judging matters of war and peace. For it is precisely the characteristic of modern weapons that they cannot be used selectively, cannot be used in a libertarian manner.”
The defense contractors of which Maybury speaks do not make handguns. They certainly do not craft feathers for bows. They manufacture weapons whose destructive power cannot be pinpointed accurately to the proper and intended target. We have become inured to the term “collateral damage.” Collateral damage: the killing of innocents and non-combatants.
The weapons Maybury advocates that others invest in, the use of which he tries so sheepishly to defend in the previously linked comments, kill far more innocents than they kill of the guilty. These are not weapons the use of which are morally neutral – just depending on the intent and goodness of the person pulling the trigger, if you will. These weapons, as a regular and expected outcome of their use, as an inherent feature based on the designed capability, kill innocent people.
It is immoral to voluntarily choose to profit from the trafficking in such goods.
