What was one similarity between the encomienda and repartimiento systems of spanish colonial america? both encouraged american indians to become loyal spanish subjects. both american indians by providing them with food and shelter. both forced american indians to work for colonists as farmers and miners. both gave american indians the benefits of a christian education.

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!
