Lies and propaganda

I just found out that propaganda is killing the world slowly but steadily. Why must man tell a lie to exist in the comity of Nations and stand back to criticize others for the same offense? The world has lived a lie from the beginning. Self deception is a form of delusion and has catastrophic consequences. We are witnessing the outcomes of our lies over the centuries past. The wars being fought around the world today are products of these lies. SAD!'!!!!!!!!!!!!!
