I mean 'liberation' is probably not what the people of Aleppo are calling it (although a lot maybe are) but I don't think we should underestimate the joy and relief that many (hundreds-of) thousands will be overcome with today.
At the very least, and for the first time in four-years and five-months, people can start to rebuild some sort of life without constant sieges, air-bombardment, shelling, hoarding, looting... etc etc etc.
