I do not think that the stan” countries pose a threat. The reason why many of the stan’ countries are under Moscow’s sphere of influence. The Middle East is not a threat because most of them get their weapons from Moscow.
I agree, and should have taken the time to say what I meant more clearly. The attack will be a non-state actor, who is either based in or comes through a 'stan country. Could come through Chechnya, Georgia, or a Baltic state, too. The Norks might be behind such an attack, but no state/country is going to want to be associated with it - Russia will exact revenge.
“The Middle East is not a threat because most of them get their weapons from Moscow.”
By this logic, Iran is not a threat because its weapons are American.
