Russia has long had several key strategic goals: the first is to create a buffer between their heartlands which you see in OTL with the creation of the Warsaw pact and their long long ownership of Ukraine, the Baltics, Finland etc. Second is about maximising their reach on the world stage, this is done by securing coastline or key points of access such as the Bosporus straights, outer Manchuria etc. These goals are pushed for by the imperial Government, the Soviets and even today under Putin.
First question that needs answering is how the Russians hold all this together because a fascist movement emerging in the 1910's-20s is going to have to contend with nationalism in Ukraine etc. To counter this I'd suggest that a fascist movement is likely pan-slavic in order to gain support from the Ukrainians and Belorussians. This obviously then adds more dimensions to their foreign policy goals as now they will seek to unify up with other Slavs in Poland, Serbia etc. Other regions such as Germany, Greece, Turkey etc will be satellites.
In keeping with the previously mentioned goals the Bosporus will be annexed, furthermore Armenia with be vastly expanded and Turkey reduced. This guarantees the Russians access to the Med, and solidifies their access to the middle East while taking full ownership of natural barriers in the Caucuses. Persia too will be reduced in size and established as a Satellite to secure access to the Indian Ocean. I'd suggest Manchuria is also probably annexed off the Japanese, Korea is puppeted and Japan is weakened in some way - economic dependence is probably one main method.
German east prussia, as with OTL, would be annexed in order to solidify control of the Baltic. I'd suggest Scandinavia is subjugated, if anything just to ensure Russia can access the North sea, in the later 20th century grabbing Iceland would be of huge strategic advantage to them. Grabbing Chinese ports would be the final bonus land grab.
Other than that honestly I don't think Russia actually needs allies, if you throw in a communist Germany you're looking at a very easy war for the Russians. If not the state will probably be much more militaristic than the soviets pre-nazi Germany which strengthens their position if Germany invades. Power wise I'd say they're likely unstoppable for most of the early 20th century, if they can get their navy right they'd dominate Eurasia and Europe. A NATO style situation is probably all that saves western Europe from being under heel to some degree.
