In this sense conflict resolution training is FOR people who are, or potentially will be, like us. If this does not apply, then is it for ourselves, such that we earn from it or feel better from it - some sense of having tried to make something better. It denotes warmth, food, infrastructure, shelter from storm and flood and, indeed, police on the domestic level. At the national level it means armies, civil defence, employment policies, etc. The same may be said of trade or development - say the word and it has acceptable meanings on several levels.
Conflict resolution has no such semantic credibility.
It is associated with community meetings, with business negotiation, etc. And yet here are two examples where resolution took place on the international level. You may wish to amend this list yourself. Whether such activity can mollify societal instability or entrenched group hostility, however, is another. Herein lie many questions.
