What's the matter with you, Tousi? Which of those just agreeing with each other that the world would be better off if wars never existed do you hope to convince with reality and reason?
I remember the same empty words and oblivious nods from the absolutely clueless when troops were jerked out of Vietnam. It left dictators free to murder half the population, spreading to adjacent countries.
I think the smarmy line was, "What if they gave a war, and nobody came?"
A better rhetorical question then and now might be, "What if men, women, and children cry out to live free from tyranny, and we pretend to be deaf and run away?"
