These new, unconventional tactics have certainly got western strategists scratching their heads. So much for investing in radar and missiles to detect and defeat ballistic missiles etc - the threat has gone low-tech and low-altitude.
Interesting comments about the relative costs & availability of defensive missiles vs the inbound threats, be it drones or whatever. Even the Israelis only use Iron Dome on projectiles which are heading towards populated areas - anything heading towards open country is left alone.
