MTG:
Thanks for your comments.
As I understand Russo, he thinks the Cubans encouraged LHO to assassinate JFK.
Russo stops short of saying, "I have evidence of Cuban intel on-the-ground cooperation with LHO on 11.22."
In fact, I have no such evidence either.
What I have is my layman's review of the Z-film, showing JFK shot at ~Z-222, JBC at ~Z-295 and JFK at Z-313. So I contend a lone gunsel armed with a single-shot-per-bolt-action rifle could not have perped that JFKA alone.
I agree with you, the mostly likely jFKA co-conspirators are Cubans, whether Alpha-66 or G2/DGI, or double agents.
