The left in the West are confused and split over Syria. Some on the left support Bashar al-Assad and see him as some anti-imperialist vanguard, whilst others wholeheartedly back the rebels, ignoring the Salafi religious extremists that have infiltrated the movement.
The idea of supporting the anti-imperialist global South has long been prominent amongst left-wing thinkers, but since the Arab spring it has led some to support the likes of Gaddafi and now Assad. The thinking goes a little like this: Bashar is kind of bad, but the West is worse; if Bashar falls then the West benefits, therefore the Syrian people should accept him as their leader.
