The specific values were and are 仁 信 義 礼 智. Benevolence/humanity, Truth/trust, Righteousness, Etiquette/right action, Wisdom. Classic values with nothing militaristic about them. Not that the militarists didn't try to twist them, but they predate 20th century militarism by 2500 years.
Totally - and they predate the bushi by 1800 years and the rice-growing, steel-forging Yamato culture of Japan by 1000 years too.
And furthermore, my understanding of Confucianism is that it is a philosophy of acommodation and that war is pretty much out of the question.
