These 'rebels' have got modern arms and are very well trained if they are capable of several month's fighting against a regular army. How is that?
The 'free' and 'independent' media maintains that Asad fights with his own citizens. If so, his soldiers must be totally incompetent.
Or, he fights with some well trained and armed mercenary force that is acting as 'Syrian freedom fighters'.
What 'truth' are you ready to believe in is up to you, but what concerns me - everything is crystal clear.
