Saudi has amassed 350,000 troops and 20,000 tanks on its northern boarder.

There is a 200+ kilometer traffic jam headed into Crimea of Russian military convoys. Russia's policy is to use tactical battlefield nukes if their assets are in threat to being overrun. I tink if 350,000 troops and tanks invade Syria via Iraq or Jordan Russia will first strike with tactical battlefield nukes to erase the threat.

This thing will go nuke right off the bat.
