If its nonsense, then it's because the Italians had a capable air droppable division ready to go, and that assessing the amphibious capacities of the Axis at the time provides a grim picture for Malta. At the least, an early, say 1941, assault on the island is a probably axis victory.I am not sure why it is nonsense, it takes time to train paratroops to throw themselves out of a perfectly good aircraft AND to do all the combat stuff on the ground, Malta was not a friendly place for gliders either as lots of small fields and rocks everywhere. As for there being no Divisional drops post WW2, there were no real opportunities. The terrain in Korea excluding the coastal plains were not really conducive to large scale para drops and only the US could have done this and subsequent wars didn't really offer opportunities or a need for divisional para insertion, to my mind the only proposed operation would have SOUTHCOM divisional paratroops inserting into the Gulf to defend against a Soviet attack post Afghanistan or whatever the Russians cooked up for WW3.
The Germans could have probably mustered a solid brigade+ for air drops, meaning that they were significantly reduced from their Crete drops. However, viewing the Axis capacity holistically must include the Italians too.
