As many of you no doubt know, some people (did you know even 3 days after Hiroshima?![1]) likened Tolkein's One Ring to the power of the atomic bomb developed in the same era: a technology molded by hidden genius, capable of unspeakable power so deadly it must actually /not/ be used, but instead, must be carefully guarded by a small band until it can be destroyed. So that true peace is possible again.
Tolkein of course denied this[2] .... and the timing wasn't right[3] and ... he wasn't a big fan of allegory[4], right?
However, perhaps he foresaw, however unconsciously or through shadow knowledge shared by others or Bentham's Panopticon[5] or seen too by Orwell' 1985[6], the coming surveillance state.
After all, in the trenches of WW1 he took his place managing signals communications in a battalion[7] and when WW2 arrived was approached to be a cryptographer, (even taking four days of preparatory courses on the subject![8] Before getting turned down[9].).
Foresaw what and shared how you ask?
That other, subtler, great Tool of Power to come out of WW2 -- the use of, and covert exposure of, signals encryption.
Encryption exerts its power in a manner not unlike one of the key functions of the rings... Anyone bearing the One Ring or the nine, who then puts on the ring -- like using encryption -- instantly makes themselves "hidden" to the mortal fellows around you.
But tragically, the prolonged use and reliance upon such power deepens and ensures ever increasing temptations and corruptions.
And such ring (encryption) use -- most unintuitively and dangerously -- makes you more, not less visible to the maker of the rings.
(Just as cyphertext stands out in a sea of plaintext.[10] (See Tor today[11], or in WW2 the then-novel phenomena known as radar traceback.[13] Or the then-novel-but-even-more-covert encryption traffic analysis[14].)
Perhaps he saw. And knew.
...
And why too the numeric gap between 1 ring, 3 for elves, 7, and the 9? Nobody knows for sure[15].
Perhaps too some linguistic colleague had whispered to the maker-of-languages (languages as obscure at that time as those of the Apache Code Talkers[16] and similarly perhaps unappreciatedly utilitarian) that... we already had "5 Eyes"[17]??
Perhaps then Tolkein knew? And passed on the word, for those willing to hear...
Poor Tolkein, he became beloved by the very Morlocks[18], err, 'easily corruptible men of middle earth" he warned about.

[1...18] Out of time! References available upon request. Or web search... Don't get me started on how this all connects to the Eye of Providence[19] or the Eye of Horus[20]! ;)

Just to expand on this, substantial portions of LOTR were written well before the atomic bomb became public knowledge, e.g. Tolkien had written first drafts of Book 4 (Frodo's journey to Mordor with Sam and Gollum) by 1944. In other words, it was already a fundamental plot point that the ring should not be used even as an ultimate weapon.
The depiction of war in LOTR is perhaps more closely associated with Tolkien's personal experiences in the war of 1914-18. The dead marshes in particular have similarities to the trenches of WW1
