Like I expected US will accused again the Russia for that incident.
If they help each other to fight the al-qaeda and ISIS I think they will be defeat that terrorist group.
The presence of the ISIS is beneficial to the United States, as they make sure that Assad is devoid of the oil revenues from Eastern Syria. The Americans have been tolerating the ISIS for quite some time now.
But it can not be said that all the terrorist organizations of the world were created by America. This is absurd. It is the American people who suffer more from terrorist acts.
