The last two points you made really struck me simply because I really think they nail these problems on the head quite succinctly. Wars are terrible, destructive and complicated, but they tend to end pretty quickly (few exceptions aside) because the people involved in their absolute majority don't want the disruption war brings to an otherwise comfortable (if imperfect) normal state of existence. The project "warzones" of large urban areas are themselves the comfortable state of existence for millions of their inhabitants. And thus no matter their their nastiness and miseries, just as you mentioned, attempts at positive external change are in a way analogous to war actually, because like war, they're the external and mostly imposed disruptions despite their good intentions. No amount of money and resources being thrown at urban blight will easily change things without bearing this in mind. This is not to say that resources for improving ghetto life should be cut off, but how they're attempted needs to seriously be reconsidered.
