Iranian drones have done nothing to prevent the US and Israel dropping gravity bombs en-mass over their capital right now. JDAMs and unguided munitions are still far cheaper for the explosion size than any drone today. That's not the situation in the Ukraine war on either side.

The US has used one-way "drones" since the 80s or earlier. The entire Gulf War in the early 90s featured a ton of tomahawk cruise missiles. The only real change is that the new shaheeds are way cheaper, slower, and smaller, but can be spammed in larger numbers.

I disagree. Iranian drones have taken out a lot of US sensing capabilities in the theater, from ground-based radars to AWACS planes, in addition to some logistical support like refueling tankers.

That has made US overflight of Iranian territory uch riskier than was expected at the beginning of the conflict, and it's notable that the US has continued to rely heavily on stand-off munitions.
