It's nearly impossible to verify that because:

1) Most of Buddhist scripture is not translated to modern languages

2) There is so much of it. Which Buddhist scriptures? Zen? Theravada? Tibetan? Tantric? It's hard to say which text is representative of Buddhism as a whole. Some people say all of them are (except when they disagree).

I'd encourage you to wonder if that's the right question to ask. In terms of International war and politics, do the words themselves matter more than how they're used?

In most cases, Buddhists kill others in the name of compassion. It is compassionate to kill a misguided (or Muslim) person and give them the chance to reincarnate as a Buddhist. To me, that's more fucked up than justifying murder by twisting the definition of something like Jihad.
