这是个好问题！
首先，基督的教导基督的榜样是和平，绝对的和平，即使是面对暴力面对杀戮。然而，暴力却是人的罪性的一部分是这个世界的一部分。人类由暴力杀戮走向和平的过程，正是基督的真理改变人心战胜世界的这个内在过程的外在表现。基督是万王之王万主之主，是指他所彰显的真理终将在人们的心中成为主宰 - 即成为人的价值观的核心和人们行为的准绳。耶稣是和平之君的含义也大抵如此：主耶稣基督所赐下的和平（准则）终将为人们所接受，并因接受而拥有。
其次，美国是个基督教国家，却并非是基督之国。体认神所赐予人的自由意志以及主耶稣基督所彰显的宽容与饶恕精神，美国是建立在信仰自由的基础之上的。所以美国不仅有基督教，而且有伊斯兰有道教佛教印度教，甚至有法轮功有拜撒旦教。美国的国家行为代表其国家利益，并不代表基督教的信仰。
即便如此，在基督徒的推动下，美国和其他西方基督教国家可以说一直在不断地对自己的战争行为反省。其政客基本上必须是在能够用自卫（比如阿富汗战争）或者保护无辜的弱者（比如伊拉克战争）来说服民众的前提下才有可能参与战争。
最后，基督徒并不是基督，基督徒也是罪人。除了极少数“基督教基本教义派”，现在还很少有人能在自己的安全自己的生命受到威胁时奉行零暴力原则。比如前面有帖子提到使徒彼得就曾经因为拔剑自卫（更确切地讲是保护耶稣）而受到耶稣的责备。
基督是和平之君，基督也是慈爱的主。他统治万国的方式，并不在乎命令，而是以自己的舍生，为人类树立一个可以效仿的榜样。承认耶稣基督是道路真理生命，认他为生命之主，愿意效仿他的，就是基督徒了。人人都效仿基督的榜样，和平就必然降临人间。 飞兄可愿意从自己开始从现在开始？
美国并不是个基督教国家。 美国所有的国父没有一位说过美国是信教的。。他们甚至是反抗基督教的。
[Benjamin Franklin]
"When a religion is good, I conceive it will support itself; and when it does not support itself, and God does not care to support it, so that its professors are obliged to call for the help of the civil power, 'tis a sign, I apprehend, of its being a bad one."
[Ben Franklin, _Poor Richard's Almanac_, 1754 (Works, Volume XIII)]
"My parents had early given me religious impressions, and brought me through my childhood piously in the dissenting [puritan] way. But I was scarce fifteen, when, after doubting by turns of several points, as I found them disputed in the different books I read, I began to doubt of Revelation itself. Some books against Deism fell into my hands; they were said to be the substance of sermons preached at Boyle's lectures. [Robert Boyle (1627-1691) was a British physicist who endowed the Boyle Lectures for defense of Christianity.] It happened that they wrought an effect on me quite contrary to what was intended by them; for the arguments of the deists, which were quoted to be refuted, appeared to me much stronger than the refutations; in short, I soon became a thorough deist"
[Benjamin Franklin, "Autobiography,"p.66 as published in *The American
Tradition in Literature,* seventh edition (short), McGraw-Hill,p.180]
"I have found Christian dogma unintelligible. Early in life I absented myself from Christian assemblies."
[Benjamin Franklin, in _Toward The Mystery_]
"I cannot conceive otherwise than that He, the Infinite Father, expects or requires no worship or praise from us, but that He is even infinitely above it."
[Benjamin Franklin from "Articles of Belief and Acts of Religion", Nov. 20, 1728]
"Belief in a cruel God makes a cruel man."
[Thomas Paine]
"Of all the tyrannies that affect mankind, tyranny in religion is the worst."
[Thomas Paine]
"As to the book called the bible, it is blasphemy to call it the Word of God. It is a book of lies and contradictions and a history of bad times and bad men."
[Thomas Paine, writing to Andrew Dean August 15, 1806]
"...Thomas did not believe the resurrection [John 20:25], and, as they say, would not believe without having ocular and manual demonstration himself. So neither will I, and the reason is equally as good for me, and for every other person, as for Thomas."
[Thomas Paine, Age Of Reason, pg. 54]
"The study of theology, as it stands in the Christian churches, is the study of nothing; it is founded on nothing; it rests on no principles; it proceeds by no authority; it has no data; it can demonstrate nothing; and it admits of no conclusion."
[Thomas Paine]
"The continually progressive change to which the meaning of words is subject, the want of a universal language which renders translation necessary, the errors to which translations are again subject, the mistakes of copyists and printers, together with the possibility of willful alteration, are of themselves evidences that the human language, whether in speech or in print, cannot be the vehicle of the Word of God. The Word of God exists in something else."
[Thomas Paine, Age of Reason]
"The adulterous connection between church and state."
[Thomas Paine, _The Age of Reason_]
"Whenever we read the obscene stories, the voluptuous debaucheries, the cruel and tortuous executions, the unrelenting vindictiveness with which more than half the Bible is filled, it would be more consistant that we call it the word of a demon than the word of God. It is a history of wickedness that has served to corrupt and brutalize mankind; and, for my part, I sincerely detest it, as I detest everything that is cruel."
[Thomas Paine, _The Age of Reason_]
"That God cannot lie, is no advantage to your argument, because it is no proof that priests can not, or that the Bible does not."
