I thought it was clones vs clones.

Obi-Wan's old name sounded so much like (as in Artoo) a phonetic transcription of a registry code, that maybe OB1 was a clone too.

I thought could have resulted in the official outlawing of clone technology to mass produce slaves and armies resulting in droids taking their place (like the Butlerian Jihad in reverse)

That's what I thought. Clones vs clones.

I was learning a little about the U.N. in school and on TV.

Republic=UN Senate=Assembly Jedi=UN observer/peacekeepers

The Rebellion was the backdrop conflict through the OT. I thought clones vs clones would be the backdrop of the PT.

The novelization reinforced that by declaring that droids weren't good for war.
