That being said, perhaps we find something more productive to do with our time as humans?
#1. For russia / ukraine neither side has air superiority. If one side had it, they could be obliterating the other side with a constant stream of 500 lb gravity bombs. Each of which has more explosives than 100 drones.
#2. For us / iran, the US is unwilling to risk any pilots. And iran has some air defenses in place. The US could drop bombs from up close, gravity mk-82's and jdams every hour for months. Currently they are using standoff weapons which are either minimally effective (drones) or crazy expensive (Tomohawk, Standard Missile, etc.)
One B1 gets shot down, and 4 crew get paraded around in downtown Tehran, and what little support trump has will vanish.
What am I trying to say? Drones have a place. They don't obsolete anything. The key is to have the weapons available to meet the time in which they are needed.
It would be nice if humans could find ways to not kill each other, but the reality is humans have a very poor track record and you would be a fool to not put at least some effort into defending yourself.
Rich free market democracies don't fight wars against each other.
The greatest failure of the past 20 years was the belief that if we open up trade and grow rich together, rational self-interest will lead to liberalization and peace. Instead, it just gave our enemies more resources to spend on self-destructive imperialist ambitions.
Economic warfare also does in fact kill people. Denying a population, e. g., Cuba, the ability to access medicine/food kills humans just as well as a bullet in the long term.
There are various other ways this causes suffering. Different forms of warfare are still warfare, even if you don't to hold a gun for all of them.
Being "rich" also requires someone else to be "poor".
Market democracy is not perfect but it solves 90% of the problems we'd have otherwise.
