But the difference is that the major exporter of Panturkism is now in the USSR, and the only major Turkic area still outside the USSR is relatively easily brought into its orbit, Sinkiang/Uighurstan. Furthermore, promoting Panturkism could bolser Soviet aspirations in Iran, Afghanistan, Pakistan, and the Balkans.
Re. Iran and Afghanistan they would have to pander to pan-Iranic nationalism, same with the Krygyz peoples. I'm not sure it will work too well in Iran + Afghanistan + Pakistan. Heck, Kurds are an Iranic peaking people technically (I guess Ataturk's claim that Kurds are 'Mountain Turks' wont get too far or wont get propagated in this TL).
Also, I wonder how Turanism would work in the USSR, I mean the Soviet Union didnt make itself a Pan-Slavic organization willingly or intentionally, it just ended up falling that Slavic countries ended up joining en masse the Soviet Bloc or were otherwise annexed. USSR even banned some pan-slavic organizations or they had to operate underground. Post-collapse those sentiments came out again. Also the whole 'soviet union becoming slanted towards russians unfairly' stick that works against pan-slavism in soviet bloc.
If the USSR had a tsundere, leaning towards disdaining relationship with panslavicism i dont think theyll go all 'turan lol
