It attempts to answer the questions:
Does Buddhism permit the State to build and foster an Army?. Can a good Buddhist be a soldier? and can he kill for the sake of the country? What about the 'Defence' of a country.? When a ruthless army invades a country, does Buddhism prohibit a Buddhist King to defend his country and his people? If Buddhism is a 'way of life,' is there any other way for a righteous king to battle against an invasion of an army.?
From the above it is clear that contrary to the popular belief the Buddha has not rejected or prohibited soldiering as a profession or occupation and the right of a king or a government to have an army and to defend one's country and its people. In the contrary the Buddha has expressly recognized the necessity for a king to have an army and providing protection to the subjects of a country has been recognized as a prime duty of the king .
