Russia’s economy is almost entirely based on oil. The Saudis can cause massive problems for Putin by under selling in their markets and weaning Europe off Russian oil. Now if they could only get natural gas to Europe too.
Russia is already in Syria. Wouldn't take much for their planes to accidentally stray off course and bomb the wrong strategic oil field.
WHOOPS!!!
Hey look...oil prices rose!
Why'd that happen?
Go Russia!
