2a) In April 1961,the Bay of Pigs occurred. During the Bay of Pigs there was an attempt to overthrow Castro. With means that they tried to get Castro away from his leadership and get a new leader to rule over Cuba. Not it is his brother that is in power. The exiles received training from the CIA, they did not only get help from the CIA but the CIA also provided weapons for the exiles forces. Kennedy was also in support of the exiles. And at the end the USA helped the exiles that were forced out by Castro to get back in the country.
b) Kennedy decided to blockade Cuba in 1962. He did this by a naval blockade. He did this because he did not want the USSR to send any more arms or nuclear weapons to Cuba. Kennedy also decided to blockade Cuba to make a non-passive way, but in the same way have a non-aggressive solution. This helped to ban any soviet nuclear weapons that were tried to get smuggled into Cuba. This was supported by the US. There had already been a call made to the USSR not to bring any nuclear weapons to Cuba anymore. Kennedy provided a blockade because he did not want to have to go to war with the soviets. He had already provided all his soldiers but there were about 40,000 soviets soldiers. If he would have went to war with them a lot of blood would have been spilled and there would have been a nuclear war.
