Beware overdrawing lessons learned from Ukraine. No doubt there are some, and really good ones at that...but the world's best and largest militaries aren't for a second thinking "oh, hey let's get rid of all our high end stuff for this cheaper not as good stuff."

Love or hate Israel, they've definitely done a number on Hamas, Hezbollah and Iran in a very short time that has been both highly effective and definitely not low tech.

Mixing the two: The fact of the matter is find a drone factory anywhere on the face of the planet, if the right military decides to blow it up, it's gone. Ukraine, for many reasons, doesn't get to wage much of a war on Russia. They are pretty much on the receiving end only.

What capable militaries are learning and adapting to is don't use expensive stuff to defend against cheap stuff...and that is rapidly occurring. Warfare is the ultimate rapid learning environment...not wanting to get killed tends to be highly motivating.
