Che helped set up a government that incarcerated thousands for nothing more than their political views. Che helped set up a government that has starved thousands through grain confiscation and retaliatory punishments. Che did help some people, but his values are opposite the American values of liberty.
Che's ultimate dream was to start a revolution to topple the American government, so I'd suggest a bit of studying before asking another question of such foolishness.
I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
