I'm left wondering about two things:
1) How this would reflect on JFK's presidency, if he were to still get assassinated in this ATL. Because this was before the Cuban Missile Crisis, one of his defining moments, if not THE defining moment.
Probably depends on how it all turns out in the end, post-Invasion. If it turns out to be something like Iraq is today, it'd just give the more fuel to the anti-war movement, if not create it a tad bit earlier than in OTL. Specially once Vietnam came rolling in.
But if it turns out to be a really decent, if not great, democracy, this would probably be one of his greatest accomplishments, specially during the Cold War.
and...
2) How would the Soviet Union react?? In and around this time, new Communist countries were popping up like crab grass, granted not all of them were buddies of the Soviet Union, but they WERE willing to give Cuba nuclear missiles in the OTL, (granted AFTER Bay of Pigs) which makes me wonder how they'd react to seeing Cuba's Communist Leadership fall.
