Since he told people to turn the other cheek if someone hit them, said that his kingdom was not “of this world”, and rebuked his disciples when they wanted to call down fire on people who didn’t welcome them, I think he is not a fan. And since wars are about greed and power and he was about generosity and humility, again he’s gotta be antiwar. The OT God was given a bad rap by the ones who wrote the history. They blamed God for stuff the Other guy did. ::insert devil emoji::
Jesus himself quoted OT passages and LEFT OUT the smitey bits.
