Also, love probably wouldn't work as well as one might think. People who love each other end up in violent conflict all the time, just ask any cop.
I think you're looking for a "mutual respect and acceptance bomb".
I suspect that a large portion of the conflict between people who "love" each other is because one wants the other to be different.
However, I recall that there are several ancient Greek texts that reveal that "regimental love" was a known phenomenon throughout Greece.
