There is no legal case whatsoever because the Assad regime enjoys the confidence of 2/3rd’s of his people and the violence originally came from outside using American, British and French special forces to arm and train assorted Muslim fanatics financed by Arab dictatorships like Saudi Arabia and Qatar which are hardly models of democracy and tolerance.
Effectively we are attempting to invade Syria using proxy forces and mercenaries to usurp a nasty but legitimate Government that stands in our way of bigger geo-strategic objectives, namely controlling Eurasia.
The case strengthening that Dr Alf refers to is only possible if Bashir Assad commits so many war crimes that he loses his mandate to govern and his people decide to overthrow him.
Regardless of what he has supposedly done, that has not happened so Syrians must be left alone to determine what happens in their own country.
What will happen in practice is that the case will not be strengthened but we will pretend it has been on the basis of fabricated evidence as happened with Iraq and Vietnam, 20 years ago and 50 years ago respectively.
