Why? Because we can end world hunger with 10% of what is spent on arms. Because eliminating wars and violence means leaving human pre-history behind and taking a giant step forward in the evolution of our species.
Because we are accompanied by the voices of all the war-torn generations that came before us. The echo of their voices still resounds throughout the world, wherever armed conflict leaves its sinister memorial to the dead, disappeared, disabled and displaced. Because a “world without wars” is an image that opens the future and seeks to become reality in every corner of the planet, as violence gives way to dialog. The moment has come for the voiceless to be heard! Out of agonizing and urgent need, millions of human beings are crying out for an end to wars and violence. We can make that happen by uniting all the forces of pacifism and active non-violence worldwide.

And why the hell not? How long will we let governments bamboozle us into killing each other?
