This.
For example this. If there's an economic dislocation in the '30 (and there probably will be) the country could develop it's own form of authoritarianism. Which would almost certainly include Pan-Slavism and anti-Semitism. Sigh, the more things change, the more they stay the same.
In general I'd expect a fascist Russia to be aligned with other authoritarian states and/or those without areas of geo-political conflict. Russia and Britain were traditional rivals (e.g. Central Asia) so even if they had similar political systems in the absence of a common threat (the Nazi analogue) I could see them being hostile towards each other. Japan is a traditional enemy, and looks on Russia as room for expansion. China is a possibility.
In my EDC Russia (then Social Democrat) was coup'd by a grand coalition of extremists that unified around a programme they could all live with: a windy mix of nationalism, corporatism, anti-liberalism, anti-socialism, social conservatism and reactionary Orthodox Christianity with generous helpings of militarism, anti-Semitism, xenophobia and the Manifest Destiny of the Slavic Peoples to rule Eurasia....
They also began a rather brutal but undeniably effective programme of forced draught industrialisation and military expansion. And started the Eastern War.
