Currently in the midst of pulling sources revolving around Soviet response to US nuclear testing/advancements (from early thermodynamic tests and ADMs or Davy Crocketts to IRBMs and such).

While there exists quite a bit of sources from the US side, there's understandably a paucity of first hand Soviet information, or at least less transparency in finding it.

I was wondering if anyone had access too, was aware of, or knows of a practical alternative to something akin to a Soviet Military open source database, or perhaps a curated source of military leader public statement's on the US.

Thanks for any help! This is surely an opaque area of research and I don't expect to find something so easy, but any insight is appreciated.
