I don't think he means the West. I think it could mean Ukraine, N. Korea, Syria, etc.
His spokesman said basically that a country that had claimed to be their friend for decades sponsored this.
Likewise I think the Pravda spin is either offbase or mendacious.
If Putin is going to claim "the West" did this then he is clearly off his rocker.I don't think he is. I sure hope not.
Also, it would not be in our interest to start an ethnic war in the Caucuses. Only a very sick person would want that.
My current thinking is that he was referring to the Austrian and German press calling for Russian nukes to be put under international control.
