Aid trucks are waiting to enter Syria's besieged Eastern Ghouta, as the nation's civil war slides into its eighth year on March 15th. The war is considered one of the worst conflicts in recent memory. Millions of refugees are stranded around the world, and nearly half a million have been killed. There's no end to the conflict in sight. Estimates show the government of President Bashar al-Assad now controls over 70 percent of the country.
