This Erdogan, a turkey for Christmas, needs to be taught a lesson he will never forget. He is a staunch supporter, in fact backing, of I.S. that he is unashamedly showing that support by bombing the Kurds who have successfully shown IS to be normal and fearful. Turkey should no more violate Iraqi or Syrian airspace for any reason, not even as much as in 10 seconds. Russia should down two Turkish jets in place of their own.
