It was fast because terror groups retreated from area without a fight, otherwise it would be a hard battle and a high density urban area. Same should be done for rest of Aleppo, make them retreat in fear of getting besieged. There should be a Homs like scenario.
There are 3 options:
1- Laying down arms and being forgiven (as Assad ordered yesterday)
2- Getting out of besieged areas with their arms without a fight
3- Being starved to death.
Meanwhile civilians are given free passage to leave eastern Aleppo while militants are preventing many from leaving.
