The “humanitarian war” instinct persists even after two decades of the horror shows that followed the invasion and occupation of Iraq by the US and UK; the western-sponsored butchering of Libya’s Muammar Gaddafi that unleashed a new regional trade in slaves and arms; and the west’s covert backing of Islamic jihadists who proceeded to tear Syria apart.

In fact, those weren’t really separate horror shows: they were instalments of one long horror show.
