The story of the tactic applied by the Soviets during the earliest days of the Lebanon chaos is a case in point. When three of its citizens and their driver were kidnapped and killed, two days later the Soviets had delivered to the leader of the revolutionary activity a package containing a single testicle that of his eldest son with a message that said in no uncertain terms, never bother our people again. It was successful throughout the period of the conflicts there.
However, since the 2003 Moscow Theater seige disaster, it seems like the Russian response to terror has been tepid, at best.
I think that’s about to change.
