A democratic and fascist path of course, more industry focuses, more focuses about spreading the revolution

By getting trotskye you should be able to unlock a new branch in the national focus tree that will allow you to adapt the Trotsky ideas which were to start revoulotion across the globe.

Here is an explaination of what would happen under trotsky (Its a video) https://youtu.be/KTHnTh6bNwc?t=7m32s

Path for Nikolai Bukharin, exanded aid to communist parties in other countries, intervention in China

maybe a new five year plan that would cause extreme death that would give large contruction bonuses but give -5.00% recruitable government, and then it goes away in 5 years, and a national spirit of the ukrainian farmers figthing the soviets and you supress that giving less manpower in that region but getting factory output up. You could also get the white generals back in one of the facist path and another where you bring Kirill back as Czar

Jebs comment is brilliant agree with loads. Soviet union changing ideology should only be possible through civil war though to reflect the entrenchment of the party at this point. Facists should have a choice between tsardom and parliament. Again Democrats get trade relations with western powers in their tree. Communism should give best options for industrialisation but a negative effect to manpower, as Jeb suggests, should be offered to counterbalance major rewards.

Haokh idea is perfect i say
