What immediate actions did fidel castro take o upset relations between cuba and the united states

After Fidel Castro came to power in Cuba, he did two things that upset the United States immediately, he implemented the communist doctrine in the country, and he allied with the Soviet Union.

The implementation of communism in Cuba meant that everything that was private went into the possession of the government, including lot of companies that were owned by US citizens. That move was seen as robbery by the United States, as their citizens literary got their possessions confiscated without being paid anything.

The alliance with the Soviet Union upset and scared the United States. That move meant that their arch enemy will have influence over the island, and also probably make a military base just right of the coast of the United States, so that put them in a very bad tactical and strategic position.

hola:

ef0: daños leves. algunas tejas caídas y otras pequeñas piezas de los tejados arrancadas, algunos daños en canaletas, ramas de árboles rotas y algunos árboles poco profundos arrancados. los tornados que no causan daños visibles (por ejemplo aquellos que se producen en campos abiertos) se valoran siempre como de ef0.

ef1: daños moderados. tejados seriamente despedazados, caravanas y casetas volcadas o seriamente dañadas, perdida de puertas exteriores y ventanas y otros cristales rotos.

ef5: daños increíbles. las casas fuertes pueden quedar arrasadas hasta los cimientos, las estructuras de hormigón armado dañadas críticamente, los edificios altos sufren graves deformaciones estructurales. devastaciones increíbles.

y según esto creo que puedes sacar tus conclusiones. y la verdad la escala ef10 si no se decirte por que no la eh visto o mejor dicho estudiado. espero que te sirva. suerte.
