Violence is actually merely the result of all the "No's" and "Dont's" imposed over us by society. Violence is the outlet of frustration or anger which has accumulated over many years due to the lack of Love we experience in the world.
Whenever we follow our Heart we will get back a reflection of "yes, it is possible". It lies WITHIN. Revolution starts within. The moment we realize this we have anchored the inner Faith and we can always resort to it. Any "no" is not ours but comes from external negative manipulation of "not being enough".

Regarding war, putting gloss on conscription by saying it is an honor to partake in war for one's country, costing thousands of lives is only one of myriads of ways the people have been manipulated. Tyranny cloaking as democracy...

Best wishes!
