the theme of this thread is about Jesus' pacifism teachings and practice which no one can deny.
All you are doing is coming up with all kinds of excuses which is very lame.
When God calls His people to war, they cannot lose- this is a very strong theme in the Bible. In fact, this got to into the heads of Catholics during the Crusades.
With Rome, however, they would have destroyed the Jews. The only way they would win against them is if God Himself came down in a like manner of the event at Sodom. With that being the case, God decided to have both Jew and Gentile take Rome through other means, and that's exactly what happened.
You, however, are using that as a way to teach perpetual pacifism.
