For all the words uttered about urgent, vital issues at this week's Democratic presidential debate, one was missing: Syria.
The war in Syria has gone on for 9 years.
At least half a million people have died. More than 5 million Syrians are now refugees. Almost another million have had to flee their homes in the Idlib region just since last December, as Bashar al-Assad's army, supported by Russian air strikes, has tried to bomb and shell the people of the province into an obliteration from their own country.
