Israel fought a few thousand poorly trained and poorly armed guys, the outcome was predictable. How would they fare if an enemy could deploy 10k drones per day at them indefinitely? Or send 100's of drones with 5kg warheads nightly at civilian targets for months at a time, probably not well...no one could.
