I'm not very knowledgeable about the paramilitaries but you sound like you know what you're talking about, however to call the interbellum regimes "expansionist" pushes the definition (Austria and Danzig wanted Germany to expand), militarist is very dubious (they wanted military parity in definace of Versailles, which is rather understandable what with Poland threatening to invade defenceless Germany and France actually doing so), and "Hitlerian" is basically flamebait (are we talking about Slavophobi? Imperialism? War for war's sake? A desire to dominate Europe with an iron fist? What the fuck?)
Many of the parties in Pre Hitler Germany shared the same views of Expansion eastward, along with an anti jewish anti communist sentiment plus the desire to correct the mistakes of the ToV through force if needed. Further from 1928 they had adopted a three phase 15 year military expansion programme that sought to rebuild the German war economy and resource base along with the Reichwehr from the enfeebled empoverished defensive force to a offensive mechanized force that could wage preemptive war with both France and Poland if the risks could be calculated. Included in these development was a reasonable chance of winning the inevitable wider European total war. If it was needed they would break the ToV in doing so.
I don't think I characterised them as hitlerian, thats going too far. I appoligise for that mistaken impression.
