  Finally, another version of contingent pacifism can be called, following Robert Holmes, “liberal-democratic” or “liberal pacifism.”  Holmes argues that modern warfare runs counter to the values of liberal-democracy. Thus those who are committed to liberal values should not support war. Essential for this claim is the idea that “no one has a right to command others to kill, and no one is justified in killing on command” (Holmes 1999, 398). The sort of pacifism that is derived from this claim is contingent upon the fact that modern warfare involves a hierarchically organized military system and mass conscription. It is possible that war could be fought without conscription or without military hierarchy; but Holmes argues that this is unlikely in the modern world. Moreover, this sort of pacifism is contingent upon our social and political commitments. Those who are committed to other social and political ideologies may find that war and the war system are morally and politically acceptable.
