What would be a typical Christian Pacifist response to 'rampant evil' - say in the form of large scale terrorism?

>The only thing necessary for the triumph of evil is for good men to do nothing. - Edmund Burke Do Christian Pacifists tend to argue against the sense of Burke's famous quote by affirming God's Sovereignty and trusting that He will not allow evil to flourish unchecked regardless of the actions of 'good men'? or Do Christian Pacifists expect specific non-violent action to be effective in halting the advance of those committed to achieving their aims by violence without regard to the restraints of the rule of law or basic human compassion such as terrorist groups? What are some of the important doctrines of Christian Pacifism that speak to these issues and how might they be applied to real world examples such as the Jewish Holocaust of the second world war and the current regime of the Islamic State?
