Make a strong point of comparison to the American public’s support of the Vietnam war to America and the war on terror today

I need help understanding US Journalism History.

With regards to the the Vietnam War, what's the best way to explain how the power of the media helped shape public opinion, leading to democratic change in the U.S.?

why did black americans begin to become disaffected with the republican party starting in 1928?

How have African Americans played a central part in American History?
