Asaad is an Alawite, a secular strongman holding the Islamists in check by playing off Sunnis versus Shiites, and a protector of the Christian minority. If the Sunni "freedom fighters" take over, they will slaughter the Christians, probably the Alawites and many of the Shiites. Israel prefers Assad to an unknown Sunni Islamist.
For these reasons, primarily, I am glad that Russia is providing support for Asaad.
Frankly, I think we should stay out of it, but England is one of two allies (Israel) I would support unconditionally.
