What "tragedy"? The real tragedy of Aleppo was the fact that the U.S. and their Wahabist Saudi allies funded and armed the so-called "rebels" for so long. Those  "rebels" committed countless atrocities against the people that they were holding hostage in eastern Aleppo. The cowards also used the civilian population as human shields in their last-ditch attempt to stave off defeat. Now that Syrian and allied forces have liberated the city, the truth will come out about the "rebels". Unfortunately, the jihadist cheerleaders of the Western mainstream media have an aversion to the truth and will never publish it.
