The 'No' vote was probably one of the worst events in British political history for a long, long time and those who rejoice at it either don't see the big picture or their motives and political persuasion are seriously suspect.
The alliance of the USA, UK and France was bringing very heavy pressure to bear and eventually Putin would have had to step in and advise Assad to desist permanently from gas attacks. The 'No' vote has immediately taken all the pressure off Putin and I doubt he has finished laughing his socks off at the disarray of the alliance. One has to wonder where Milliband takes his instructions from.
