This Times of Israel states that Israel could have captured the entire West Bank in 1949 had it desired to do this:

Anyway, I'm wondering--what about having Israel capture only the southern West Bank in 1949? Was it a mistake for Israel not to do this?
Capturing only the southern West Bank would have given Israel additional living space--which it needs given its rapidly growing overpopulation problem nowadays--while also ensuring that Israel wouldn't be overwhelmed from putting too many Arabs inside of its territory.
What are your thoughts on this?
