If you have enough people, bulldozers, and money to throw at the problem, sure.

Does Israel have that available? I can't really say.

Some of the things that would factor into how many people, bulldozers, and money you'd need to do so

How big of a city?

What kind of construction are we dealing with?

How much are we willing to ignore worker safety and such?

How much of that city has already been partially demolished by other means the time the bulldozers get there?

How bulldozed does it need to be? There's a spectrum here that goes from something "crashing a bulldozer into every building enough times to make it unlivable" to "everything completely leveled, and all the debris cleaned up, neatly pushed into piles, loaded into trucks, buried, etc." Do we need to bulldoze the entire city? Or just most of it? Or maybe just enough that pretty much every block is looking pretty wrecked? Or maybe just all of the structures and we can leave parks, parking lots, streets, and other open spaces intact?

Do we have to be picky about using specifically bulldozers? If the end result is essentially the same, you could also use excavators, guys with sledgehammers, cranes, wrecking balls, explosives, airstrikes, artillery fire, etc. there's plenty of other options to work into the mix if we don't limit ourselves to just bulldozers.
