The US initial attempts to destabilize Cuba, like the Bay of Pigs, were failures, and afterwards the Castro government became too entrenched with a large population and Soviet backed military. Invasion was no longer a tenable option.

Vietnam was a fucking disaster, a huge country with tens of millions of people and a popular communist movement. The US got involved knowing that it would be almost impossible to stop the country from going red.

Grenada was a tiny nation of 100'000 with a negligible military. They invaded like three days after a coup when the country was completely unstable. They also did it at the invitation of the country's governer general and the states surrounding Grenada. There were also hundreds of American medical students in the country so they were able to call the intervention a rescue operation to save American citizens.

Bautista was a fucking retard who had alienated the US, likewise in Vietnam Diem was like a genius/retard who actually did have a chance at getting shit right but preferred to autistically chimp out at Buddhists for no fucking reason.

>Cuba
Because Bay of Pigs failed
>Vietnam
The U.S. never tried to invade and capture North Vietnam because it didn't want a repeat of the Korean War where it invaded the North and triggered a large Chinese military response. So the U.S. was stuck perpetually defending South Vietnam from North Vietnamese attacks until domestic support faded

Grenada is a tiny island with like 100k people, which made it much easier to push around than a real country would be
also their ruling party fragmented/imploded, if they didn't coup Bishop the US probably wouldn't have had the chance to intervene.

Both of those countries right wing governments were extremely corrupt and retarded, run by crooks, and had internal factions fighting each other. The U.S. can’t prop up a regime of kleptocrats forever look at what happened when they tried to do that in Afghanistan

Cuba were able to have revolutionary unity but the war in the mountains allowed castro to advance on the capitol also
About vietnam that french plantation scene from apocalypse now director’s cut there’s things noone understands about the vietnam war and that leads republicans and conservatives to this day to get angry and claim that the united states won the vietnam war or something like that
The situation in grenada seems like part of what undid that revolution is that maurice bishop was taken out by a coup from bernard coard who was deposed in another coup by hudson austin, so that is the atmosphere that is going on when the united states is able to land an army or something like that

iirc didn't Grenada ask for US help

Regarding Cuba, they didn’t notice the obvious warning signs until it was too late. Even Batista knew Fidel had communist ties. Vietnam is more tricky though, maybe if the U.S. supported Ho Chi Minh earlier there would’ve been less of a mess there but a communist North Vietnam seems inevitable, much like the North invading the South was inevitable.

Diem was pretty even-handed. Unfortunately everyone around him (siblings (including an archbishop), supporters, businesmen, etc.) was dead-set on Catholic theocracy. In fact, his Archbishop brother is personally responsible for the ordination of a few sedevacantists and their cults. If I am not mistaken he was one of the most high ranking Sedevacantists ever.

See I have a weird view of the Cuban affair in general. The US government was for a long time acting like Castro is just joking with the communist stuff, then when the Bay of Pigs situation happened it was believed that oh, we've heard of the failed operation that must have been a decoy. Even if Castro may have been willing to go on his own way before it, afterwards he just went straight into Soviet arms.

I think the principal reason for Cuba being allowed was to prevent the rebirth of isolationism in the country and they allowed it to happen just to show that look, the ocean isn't protecting us from the commies. This is also why the missile crisis was so bad for them, before that at worst Cuba could've been used by soviet signal intelligence etc. It was a problem but not a super big one. If Soviet nuclear weapons would get in there... That was be different. This is why they suddenly became harsh over it. It was meant to be scarecrow but not actually scary, and there were chances it would become such.
