The Bosnian War had raged from 1992 to 1995, and had stopped only after the NATO led an air campaign against the Serbian backed facted, and that only after a more
moderate international intervention by the United Nation peacekeeping forces failed to stop the fighting and the massacres.
The finding that the training only condition was ineffectual at some time points, and counterproductive at others is consistent with findings yielded in other,
international universal
intervention studies, that typically show no or small to
moderate effects (Cuijpers, 2003; Roberts et al., 2008; Conduct Prevention Research Group, 2010).
