"The Red Brigades had shown themselves to be resolute and efficient, but theirs was not a victory. The decision to kill Moro created serious dissent within their ranks, whilst outside there was a deep sense of revulsion at what they had done. It is generally recognised that the crisis of Italian terrorism began with the killing of Moro. With hindsight, it therefore seems fair to acknowledge that the champions of intransigence were right: had Moro been exchanged for one or more terrorists in prison, the Red Brigades would have appeared both invulnerable and willing to compromise, with the result that their appeal would almost certainly have grown. [...] After Moro’s death, Italian democracy not only defended itself but was strengthened."
