In the last two decades, the distribution of income has

narrowed the income gap

not changed significantly

become more equal

become less equal

a peace conference held after the surrender of japan

an international conference held near the end of world war ii

a meeting of the victorious nations after the defeat of germany

a summit meeting between the united states and the soviet union

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!
