In one battle I read on the Ukraine war, Russia sent out 1000 Iranian drones at once to destroy 5 targets. They knew most will be shot down, but if 4 or 5 drones hit the target, it will destroy the target complete. That's how these drones were designed to be used, dirt cheap to make, but impossible to stop in swarms.
Even 200 still isn't a lot if they aren't coming all at once, and Israel's defense can handle that easily. They're designed to shoot down 100+ numbers or rockets, shells & other air borne targets going much faster than drones before they hit their target.
Indeed. We already have more than enough land for every human, and can probably even provide for double our global population. The problem is that wealthy already owns the majority of land, and limit its access and usage to the average citizen of his nation.
They are some exceptions of this, India and China are the two I can think of right now. But it also probably one reason they are able to have a very high dense population, people there have more access to land.
