Part 1 of my review of Newman's Into the Storm as it relates to Antonio Veciana is online. There will be at least 2 parts and possibly 3.

Nice summary, Tracy. It's a good read and well put together. As you know, Newman is throwing a lot of information out in these three volumes. It's a bit dizzying trying to follow things.
As a side comment: It does seem to me that the CIA would be very interested in Alpha 66's activities especially during the missile crisis and afterwards when the Kennedy Administration cracked down on exile activity. Newman quotes from several memos where JFK specifically expressed concerns (in his hand writing) about Alpha 66's attacks on Soviet and other foreign nationalities ships in Havana harbor.
So, the lack of documentation/evidence of this is a bit surprising to me. As you know, the US Army was interested in Alpha 66 especially for any intelligence they had on Soviet weapons/resources in Cuba.
Fonzi was, I think, a bit misleading in his Washingtonian magazine piece where he described Alpha 66 as one of the largest and best organized anti-Castro groups. That may or may not have been true later on but I'm pretty certain that in the 1960-63 period it was a small group known for its daring attacks. But it wasn't well funded - Veciana had enormous trouble getting funding from the exiles because of their mistrust of Menoyo - and splintered at least once over internal disputes.
In any case, as you suggest this is all a prelude to the big question of Veciana allegedly seeing Phillips with Oswald in Dallas. Otherwise, it's interesting history about Cold War intrigue between the US and Cuba and the Soviets. But that's about it.
