CPT does not advocate the use of violent force to save lives of its workers should they be kidnapped, held hostage, or caught in the middle of a conflict situation.
Four members of CPT (Christian Peacemaker Teams) were kidnapped by terrorists in Iraq. But given that pacifists are at best essentially useless to Humanity in General, this would really not be an actual problem. After all the terrorists could have kidnapped and eventually murder four actually innocent people.
The CPT website had an interesting question at the head of its page:
What would happen if Christians devoted the same discipline and self-sacrifice to nonviolent peacemaking that armies devote to war?
The answer for those of us who live in the real world is that Christianity would effectively become extinct.
Now, what would the death toll of CPT volunteers in Iraq be if all of them were to have their throats cut by Allah's own death squad?
It would be an acceptable one.
