Tactics used in the conquest of Fallujah would be most effective in Gaza. For example, tanks are preceded by armored bulldozers which create new roads, through buildings and other obstacles, denying Hamas the opportunity to place IED’s. Israeli commandos are experts in house to house fighting, and have developed unique and creative ways to enter buildings. They can use chainsaws to traverse through one building into the next in built up areas, by simply creating doors where none exist. Once an area has been cleared, completely level it with bulldozers to create killing zones which Israeli outposts and air power will have no problem keeping vermin free. If they wish to hole up in bunkers and tunnels, bury them alive with bulldozers. If resistance is encountered from a particular building, call in overwhelming air power to clear the building. Then bulldoze it.
Superior firepower always wins the day, if used creatively.
From everything I’ve read and what I know about Prime Minister Benjamin Netanyahu, you won’t see that happening.
