We need a solution to stop the Syrian exodus

Given that the Syrian army and its allies (Kurds, Hezbollah, Iran) are about to encircle the ISIS terrorists in Aleppo and cut off their supply routes to Turkey, the Turks have begun shelling Kurds in Syria (from Turkey) who have been successfully fighting ISIS. 

The Turks and Saudis are proposing to invade Syria in order to protect the supply routes of these ISIS terrorists.

This will potentially ignite another world war with Russia acting to support Syria, and if NATO supports Turkey in its putative illegal invasion of a sovereign country.
