Your city has almost no capability against me, and I'm not even all that powerful compared to some people. What you saw today was what the beginning of a war would be like, but on a very small scale. If you wish to survive, you need to evolve in the face of the technologically advanced world. Failure to adapt is failure to survive, we both know this. For a price, I'd be willing to offer protection for the city and provide rebuilding materials and clean-up crews.
