"Viewing the violence from a comfy couch, it is easy to conclude that "these people are animals. We can't help them." But imagine what would have happened in Los Angeles if the 1992 riots had gone on for weeks, with no police or military intervention. L.A. could have come to resemble Baghdad or Sarajevo, with Anglo, African American, Latino and Asian gangs rampaging out of control.
To extend the analogy, violence could have spread throughout Southern California. That's what happened in the Balkans when fighting spread from Slovenia, the first province to secede, to Croatia, Bosnia and Kosovo. A wider spillover was averted thanks to American-led intervention."
