What was Thomas Hobbes’s view of human nature? People are usually peaceful.
People are naturally selfish.
People are basically good.
People are normally obedient.

so, based on the research i've done. the u.s. government were always on a wild goose chase just to take down castro. he then retired his trone to his brother raul in 2008 due to some health issues. so it's obvious your answer would be:

hope this and have a fantastic day!
