Israel is geographically a very small country with a rather unique situation, and has spent eye-watering amounts of money on its arms industry with significant help of the US and Europe. In addition, their defence was very good but not fool-proof. I'm not sure how many landed off-hand, but there was some serious damage. Other defences will likely be less effective. I'm not so sure an effective missile/drone defence would work for most other countries: too much area to protect, too expensive for the advantage it gives. Protecting key cities/locations could perhaps be effective, but entire countries? Probably not.
