How could We make a difference in our lives and in other people's lives during this time in history?

By a change the events...

Explanation:

We can not stop in our way without any change like we do the same work every day or to make the same food or work all the time and do the same things every days.. Etc.. No, we should make a new events...

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:

castro had no allies from which he could receive aid.

hope this and have a fantastic day!
