The West turn a blind eye, indeed trade, supply goods and weapons to many sides in some pretty terrible wars and genocides, foremost is Burma, CAR in Africa, ignore HR abuses in China and Saudi, all happening right now.
& all very much in contravention of various UN charters.
I guess the difference is here is it gives a chance to bash Russia and Iran.
Trump, Macron and May all have domestic political problems, so a nice distraction.
