I understand that Putin's reputation as a "strong" leader is founded on escalation and ruthless retaliation whenever he is challenged, but Turkey does not have a snowball's chance in hell against Russia.

Perhaps the Turks should have read their script from
www.globalfirepower.com before shooting down the plane. Maybe they did. Maybe not. I think the real issue in Syria is to prevent escalation. That has always been the risk since Russia entered the theater.
The conventional military weakness of Russia is actually cause for concern in such encounters. Because they don't have many options of responding, that can lead to a higher propensity to revert to the only thing they have; WMD. Yet Putin is rational. So no response of a military nature is expected. They have said they will include the s-400 anti-aircraft missile shield into Syria. Sabre rattling. Nothing more.
Russia enjoys a level of impunity in what they call the Near-Abroad(former Soviet Union republics). They can run over countries like Georgia without worry really. Interestingly their invasion of Crimea has served to create a new red-line in Ukraine, that didn't exist before. They have in the process lost Ukraine; kind of.
I think they also have some freedom of operation in Syria, at the moment open game for everyone with power, especially around Latakia and those parts of Syria still under Assad.
