Don't worry, it is not that bad. The Russians won't use nukes and the Saudis haven't got that many troops and equipement and I haven't read about these "exercises".
If the exercises were true then it would be all over the alternative media and on Russia Today etc. I must admit I haven't watched Russia Today for months as I am following the Trump phenomenon.
The article is a mixture of truth and exaggeration. there is a lot of truth in there but there is also OTT exaggeration.
We are very close to a WWIII scenario but not in the way that article lays out. I think Turkey will invade Syria sometime soon under the pretext of setting up a safe zone etc and I think the Russian will probably react. At that point we will find out if we have a WWIII scenario if NATO joins in on the Turks' side.
My guess is that the Turks and Saudis are being tricked, they will enter Syria,they will not be helped and their regimes will fall. But I am only guessing.
It is dangerous times, but not as dangerous as that article says.
