But then you're not a pacifist. By definition (at least my understanding / interpretation), a pacifist considers violence unjustifiable in any and all situations.
And if you really want to go to the definition, wiktionary [1] has it as:
1.One who loves, supports, or favours peace;
one who is pro-peace.
2.One who avoids violence.
3.One who opposes violence and is anti-war.
Opposition to and avoidance of violence. Not necessarily an absolute rejection of it (though that is likely the ideal of all pacifists).In my personal opinion, abolishing standing militaries while leaving ourselves open to raising an army if the (perhaps unlikely) need arises is, while probably not a common attitude, still just a standard non-pacifist position. I am more than open to abolishing standing armies, but I do not consider myself to be a pacifist.
