Except the effectiveness of precision fires is now closer to 50% in a GPS denied environment. Now it's both expensive and inprecise.

Every hear the term "arms race". This is a constant in history. There precision weapons that don't use GPS. There are various ways to evade GPS denial (I don't know how effective they are). We will constantly be in a race of out doing each other.

There are alternatives to GPS but they are expensive. While the arms race is normal the issue is the penny hasn't dropped yet and no one wants to admit their weapons are now obsolete.

Ah, I was actually thinking about how iron dome vs Hamas rockets. Iron dome was super effective, yet a million a pop to shoot down a rocket that costs a few thousand dollars at most may quickly bankrupt a country. That said, maybe it's just one aspect of the war while in grand scheme of things highly effective guided missiles will win the war.

Not shooting them down would be more costly though.

while i agree about the importance of precision, a 3-d printed drone from a ukrainian basement workshop also hits exactly where you want it, to the point that the problem is finding out what you want
