What kind of army would Jesus form and lead?  What kind of military action would He undertake?  I think that's your answer, if you're really asking the question. 

At AnonAJ's suggestion, I recently read Merton's collection of letters to his many and various friends (Hidden Ground of Love), written during the 1960's and detailing his views on the whole peace movement of that time, which included early action in Vietnam.  Many letters to Fr. Berrigan discussed how far US policy and aims were from Jesus' Gospel and how warped our national viewpoint had become.  

With Vietnam, our shameful actions in Central America, all the havoc we have wreaked in the Mid-East, and the absolute insane stance Trump is taking with regard to North Korea, Syria and Russia, I can only think that we as a nation have become even more hawklike than when Berrigan actively promoted peace.  Those times and principals seem so innocent and naive, yet how prophetic he and his associates were in their warnings.
