Jesus was a pacifist...
Now that I'm no longer a JW I think the JW position on war and violence is weird, they are opposed to war more because of 'political neutrality' (no part of the world) then 'turn the other cheek' and 'love your enemies' which is the main reason for opposition to war in the Quakers and anabaptist peace churches (and early church history), plus they allow for some level of personal violence (as has been mentioned)
Of course they will sometimes write about 'loving your enemy' but not so much because they don't really practice it outside of a war setting (they shun their enemies)
