Couldn't this be explained by the US intelligence agencies just being bad at reading the general public in Cuba, the invasion could not have succeeded with such a small force without a general uprising and IIRC the invasion was supported by both Eisenhower and Kennedy so to claim it was some deliberate failure on the part of the USA needs extraordinary proof of conspiracy including both presidents - the US government has supported many other coups around the world. It seems more like the intelligence agency trusted their Cuban allies enthusiasm and reading of the situation too much.
