Yep - shame they didn't have the moral conviction to do the same 10 years or so ago.
America has got itself in a proper tangle over this. I can quite imagine the conversations with their Sunni allies in the ME "So you overthrew the Iraqi regime for allegedly possessing WMD, and supported the overthrow of Gaddafi who was just about to start the industrial slaughter of his people, yet in Syria, where Assad is flagrantly using WMD and killing his people in their 10s of thousands, you decide to what, exactly?" The ghosts of of previous justifications loom large...
