You’re imagining a world where this kind of tech is equally distributed. It’s not. Israel spends something like $30b/year in defense (in part due to ~$7b/year from the US). Gaza has something like $0.3b to spend. The consequence of that asymmetry is one of them has a missile shield, the other has more than 80,000 dead citizens, famine, and virtually no infrastructure left standing.
