Non-violence is the most powerful weapon
An one sided act of aggression cannot be called as war. It is nothing but terrorism. It is tyranny and cowardice in its most ugly form. Calling it a war can only be the farthest from truth and morals. Calling it as one's values is the most shameful thing to do.
The act of USA going into Iraq is no different from the acts of those responsible for the 911 tragedy. Just because you are a leader of a democracy that can't be called as a war. It is no different from an act of terrorism.
