You are implying that Iraqis, Libyans, Liberians, Rwandans, Yugoslavs, Syrians, North Koreans, Chinese, etc., are not civilized. I wonder what they would say about that?
I can't follow you.
What happened in Rwanda?
500,000–1,000,000 men, women and children slaughtered because they belonged to the Tutsi tribe. Civilized?
What happened in Libya?
A civil war with tens of thousands tortured and/or killed, sexual assaults, the combatants using human shields. Civilized?
What happened in (ex-)Jugoslavia?
Ethnic cleansing, genocide, displacement; some 130,000 killed, some 4,000,000 refugees. Civilized?
What is happening in North Korea?
Brutal dictatorships one after the other, government rejecting food help during serious famines, concentration camps for 150-200,000 political opponents, real or imagined, blessed by forced labour and risk of summary beatings, torture and execution. Civilized?
What is happening in Iraq?
De facto religious and tribe civil war, where private armies and suicide bombers kill indiscriminately, etc. Civilized?
Continue the list of civilized behaviour yourself.
Here is what I am thinking: if our military were trained with non-violent resistance tactics, and we deployed our military in Syria and they used those non-violent tactics, the war in Syria would be over by now possibly or very soon. Human beings are human beings, not matter where they are from. I am unaware that these kinds of tactics were used in any of those places. Pacifism does not mean "sit and do nothing". It means to resist injustice, but without violence. In many of those cases, the United States just did nothing at all. This kind of resistance also only works if it is organized and many people do it. But it works.
Do you really believe that turning the other cheek to murderous fanatics will achieve anything but your death?
I am sorry, but it is not a question of injustice, it is about blue murder to gain power.
Can you name one or two countries, where one side was prepared to kill all opponents and yet pacifism won (unassisted)?
As I wrote in a previous post: "
It worked for Gandhi in India - but it would not have worked, had the British simply killed him immediately after he started his movement."
Only Britain's sensitivity to public opinion saved his life. How sensitive is e.g. North Korea to public opinion? did it stop the genocide in Rwanda, the civil wars in Libya, Liberia, Congo, ... mile long list.
