The more effective the dealing with the Norks, the more Iran loses - even Putin is extra interested because dealing with the Norks will have effects on his hegemony aspirations with Syria and Iran...thank Trump for the clarifying picture.
putin will play Erdogan, while Erdo destroys his military (he arrested most of the senior leadership), then ends Turkey's membership in NATO, then destroys Turkeys economic rising and splits the country. THEN Russia will invade Turkey
Syria? iran? They are allies in dismembering Turkey for Russia.
