Jesus didn't come to setup or destroy governments. He came to show us how to live within God's will, and to redeem us from our sins that we might be restored to Him. The battle He was involved in was a 'spiritual' battle. A weapon would have been of no use nor was it needed.

I'm sorry, I don't believe this statement to be entirely accurate. I have no argument with the concept that it was a spiritual battle, but the very way in which Jesus conducted the battle would seem to indicate that, at least part of, the battle was to agitate the government or at least those in power. I don't think the fact that he caused that effect was passive, I think he realized that his actions would cause turmoil in the political arena and he thought that necessary to his cause.
