The Apostles carried swords. Self-defense is fine, as is a nation defending itself. It's a myth that Christians have to be some sort of super pacifists, and comes from a silly mis-interpretation of the Sermon on the Mount. Peter himself whacked the ear off of an official that came to arrest Jesus, after all. Jews themselves were a warlike tribe all through their history and after as wee, when they served in the Muslims' invader armies, all the way back to serving as mercenaries for Egyptian rulers in forts at the Elephantine.
the people who peddle the 'Uber-Pacifist' rubbish the most are assorted deviants and sociopaths, the types who want to toss Xians into ovens; they try and sell that nonsense to make it a lot easier on themselves to threaten Xians and when they come to march them off to concentration camps for the crime of frowning on mass baby murders and faggots cornholing little boys.
