Very few cities have ever died due to war. Even Carthage, who Rome was so pissed off at that they razed flat and salted their fields, got revived not long after the Third Punic War and was the second largest city in the western empire during the imperial era.
Likewise, it takes an incredible geological catastrophe to really kill a city dead. Enough to render the land literally uninhabitable. And humans are quite good at making uninhabitable land habitable.
No, there is exactly
one thing that'll really kill a city, and that's a lack of economic impetus. Plains farming towns are dying because there's no real room for small farming towns on the Plains anymore. Cairo boomed because of its confluence but died as through traffic shifted from the river to the railroads, which could go overland and generally went to Chicago or St. Louis instead. Cities with all their economic eggs in one basket are especially fragile: Manchester sputtered as the textile industry was replaced due to overseas competition; so has Detroit with automobiles.
And of course, a dying country leads to dying cities -- as the western Roman Empire failed, many of its major cities just up and died, creating room for minor what had been trade outposts (like Paris) to grow. Paris was, for the first
millennium of its existence, little more than a minor trade outpost where the major north-south road forded the Seine right around its fall line. It didn't become a major center until the seat of French government moved there. Meanwhile, cities like Ostia and Carthage died dead as the empire fell apart.
