just a quick check: how would you translate {papklu}? thanks,"beatnick". :-) x1 is a peace-oriented culture of nation x2, with peaceful intentions directed specifically at x3. It's not a bad choice for "pacifist". Not a good one either, though, IMO.
Actually, I was more thinking about buiding a word for "culture of peace", like in http://www3.unesco.org/iycp/ . So close to your definition I think, and indeed not really a translation of "pacifist".
