Is this statement true about Buddhists at war?

Question

In East Asia, Mahayana Buddhism elaborated doctrines that served as a basis for war. In China, for example, the belief in a future Buddha led to various rebellions to secure the survival of peasant communities, and Buddhist millenarian cults periodically rebelled against the ruling dynasty. In Japan, Mahayana Buddhism accepted the samurai warrior and set the stage for political insurrection and a number of violent confrontations among competing sects.

Answer 1

Buddhism in Japan became intertwined with Shinto and other beliefs so in that specific case the martial society that was created was not a product of Buddha's teachings.

Answer 2

I have never heard this and need to research more about it. I do know that it is a peaceful religion, but that it does allow war. Reading the auto biography of the Dalai Lama really opened my eyes to the way some Buddhists saw war to protect ones freedoms.
Thanks for the info.

Answer 3

Buddhist people never bore any arms.
