We need to think more logically when it comes to events in Syria
The Russians were in the sky in the first place because Russia is supporting Syria’s leader Assad by dropping bombs on Syria. Turkey doesn’t like Assad, but it doesn’t like Russia either. The Kurds are against Assad, but Turkey doesn’t like the Kurds.
UnIslamic State — Daesh for short, because they don’t like it — is against Syria’s Assad, but Russia is against Daesh.
