Should Christians be Pacifists or can they Fight the New World Order?

I was recently chatting with a friend about my latest hub "Why Tea Parties Wont Work" and he brought up an interesting subject that I have struggled with for years now. That is, if we as Christians know what will happen at the End Times, IE that we will have a one world totalitarian government, that the RFID chip will be implanted, that the Anti-Christ will come, you know all the stuff that goes into the End Times, should we fight against it?

I have to tell you I have thought and thought about this subject for a very long time. I have gone back and forth in my mind. And even now I don't have it fully settled in my mind. The video by Greg Laurie helped me a lot so I would encourage you to watch it. The gist of it is that we are to try to win others to Christ in our personal behavior, however, God did set up the government for good and justice is of God, therefore the military and the police force should be institutions that carry out justice. If they do not, that is another matter and one that our founding fathers and I think the bible would say we should oppose.

(Matthew 5:38) Ye have heard that it hath been said, An eye for an eye, and a tooth for a tooth: (Matthew 5:39) But I say unto you, That ye resist not evil: but whosoever shall smite thee on thy right cheek, turn to him the other also.

To do good to those who abuse us:

(Matthew 5:44) But I say unto you, Love your enemies, bless them that curse you, do good to them that hate you, and pray for them which despite-fully use you, and persecute you; (Matthew 5:45) That ye may be the children of your Father which is in heaven: for he maketh his sun to rise on the evil and on the good, and sendeth rain on the just and on the unjust. (Matthew 5:46) For if ye love them which love you, what reward have ye? do not even the publicans the same?

And to bless those who persecute us:

(Romans 12:14) Bless them which persecute you: bless, and curse not. (Romans 12:15) Rejoice with them that do rejoice, and weep with them that weep. (Romans 12:16) Be of the same mind one toward another. Mind not high things, but condescend to men of low estate. Be not wise in your own conceits. (Romans 12:17) Recompense to no man evil for evil. Provide things honest in the sight of all men. (Romans 12:18) If it be possible, as much as lieth in you, live peaceably with all men.

The previous mentioned passages are guides to how we should live our personal lives. However, should a person determine to do evil is it good or evil to try and stop them? I'm for the right to bear arms, my Dad had an entire arsenal of guns around when I was growing up and he taught his daughters how to fire them. I think we have the right to defend ourselves. I think that the state has the right to a just war and I have written about that and I do believe that the state has the authority to enforce capital punishment (although I am against it in this country because of rampant abuse) but personally I don't think we as Christians have the right to strike out offensively against anyone. That's not to say I don't support those who do think offensively and if I were not a Christian I would be right there with them. But, my beliefs keep me from going further. Am I wrong? Tell me, I would actually welcome the argument because even personal pacifism feels very uncomfortable to me.
