From the story of Jesus, do you gather the message that no more taking of lives is required sacrifice to show?

as required to show reverence to God? If so, shouldn't we begin to do the same to show loyalty to our nations? (After all, we've had 1,980 years to think about this)If so, remember to honor the old ones who killed for us(even if they are 50 years younger than you), but say "sorry, it's non-profitable nowadays,and it's not decent to donate slaughtered remains to my favorite charity", so be sure to put the 'safety' on on your weapon of common defense. Is this sensible, in-effect, a global armistice? Then what shall be our fight for each? (Note this question is not intended as religious or political)
