Say NNNNNNOOOOOO to violence

These days I suspect that we are in the midst of third world war. Day by day, we find conflicts that spread across many nations, cultures and civilizations. World is becoming an increasingly dangerous place to be. The situation is being stoked by ever increasing hunger to control resources. Later being scarce, these conflicts are here to stay.
As a peace lover, I keep asking myself - what it my responsibility in such a world?
I can't understand human civilization or lack thereof. Violence has not solved and will not solve any problem. Yet, our governments try to seek military solutions when faced with attacks. Having applied a wrong tool to begin with, they obviously see no results from their actions. Frustration and desperation coupled with lack of imagination causes them to apply the same tool again with more power and vigor than ever. Result is destruction every where.
Why do we put up with this? Why don't we say NNNNNOOOOOO to violence?
