Putin: Russia is a nuclear power, and has nuclear missiles off of Turkey?

In a roundtable interview with reporters on Wednesday, a senior Turkish official accused Russia of conducting an “ethnic cleansing” campaign in the northern part of Syria. At the same time, Russian President Vladimir Putin was reminding the world in general, and Turkey in particular, that not only is Russia a nuclear power, but that the Kremlin has nuclear-capable missiles aboard a submarine stationed just off Turkey’s coastline.

Putin’s War of Words with Turkey Escalates to Nukes and Ethnic Cleansing

I was trying to figure out here exactly what Putin was saying. The Closest I could come to making sense would be something like Putin is saying:

"Shut up about ethnic cleansing of all the Sunnis in Syria or we might nuke your ass."

I tried other scenarios in my mind but I think this is actually what he means which is a little difficult for everyone but likely is Putin's style.

No one questions Putin in Russia so I guess he thinks no one should question him in Turkey either.

The best way I can put this is: "This is going to be very difficult for Turkey to not go to war with Russia. But, going to war with Russia likely would also be suicidal for Turkey on a bunch of levels."

Because the U.S. is not going to have a nuclear war with Russia unless he nukes the U.S. Period.
