Secularize Turkey and Iran. This is certainly in line with their role as "defender of the faith" and "third Rome". This most certainly seems to have worked on Turkey (which got buyers' remorse over backing the ISIS caliphate). In Iran, the secularist party of Ahmadinejad seems to be on the rise once again, but their ascent is by no means certain. Certainly if the USA and Israel get to have their war, any nascent resurgence of secularism will be strangled in the crib.
