2. We know that during the Middle Ages the Normans conquered England and changed
everything from the language to the economic
system. How did the Normans impact Ireland?

The Normans introduced the English language to the Ireland,common law,which eventually supplanted Brehon law,parliamentary system and they built imposing castles across the land most notably king John's castle in limerick , Trim castle and carrickfergus castle.

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!
