It's even worse, actually. This attack seems to be done by a regular quadcopter, so suddenly you have to be worried about your $100M aircraft being destroyed by a $500 drone if your base security isn't absolutely perfect.

The US has plenty of bases in the area, but considering the ease of an attack and the general anti-US sentiment of the region, projecting power into the Middle East is going to become an awful lot more difficult...

Wake me up when all F35 are sitting on airfields reachable by Iranian drones and unprotected and doing nothing but waiting to be hit

V-weapons were also an encounterable weapon which could strike from beyond range. Massive boondoggle though, just a very expensive expensive way to deliver very few explosives; waste of industrial output.
