The fact that home made drones can cause such havoc to even the best funded military is an equalizer when the military with all the power is actively trying to completely eliminate the otherside.
There are no home made devices a Gazan can build that can protect from a 2000lbs bomb.
USA/NATO/allies heavily rely on Patriot AA system. Even if you disregard the prohibitive 100x cost difference, there are about 2500 Patriot compatible PAC missiles.
This is why gulf states are scrambling to get their hands on cheap alternatives - Ukraine manages to shoot down over 90% of all drones heading their way, usually it is over 400 per day in big waves.
FPV.
But I really hate the whole weaponization of these FPV drones (as opposed to the bigger fixed wings ones), not just they ruined the fun hobby that a lot enjoy, but also increased the prices for the parts. Before 2022 whenever I talk about drones everyone is enthusiastic about them, what benefits they can bring like drone deliveries and all, after that, you get a hostile reaction or the government putting you on some watchlist.
Just to give you one figure: estimates are that between 1000 and 1500 Shaheds have been downed by interceptors during last February. That's not a 100% kill rate but it definitely isn't 1% either. And they're getting better every week.
