Inspiration from Lord Buddha.

Right livelihood means that one should abstain from making one’s living through a profession that brings harm to others, such as trading in arms and lethal weapons, intoxicating drinks or poisons, killing animals, cheating, etc., and should live by a profession which is honorable, blameless, and innocent of harm to others. One can clearly see here that Buddhism is strongly opposed to any kind of war, when it lays down that trade in arms and lethal weapons is an evil and unjust means of livelihood.
