<human>: Can you give me the gist of the text in a nutshell?

I'm not sure if this is allowed but I'm not really sure what subreddit my question belongs in. I'm supposed to write a 3-5 page essay on the Vietnam War which I know next to nothing about. I really need help and I've tried Google but it's vague and difficult to understand. My question is, can anyone give me a brief, yet detailed, summary of the Vietnam war? Also, my essay should be based around some of these subjects: causes of vietnam war, anti-war movement, U.S foreign policy during war, draft evasion and  amnesty, post-traumatic stress disorder, civilians who served, weapons used during the war, drug use, POW/MIA issue, My Lai, Vietnam today, Vietnamese culture.
<bot>: Q1: Brief summary of Vietnam war. Q2: What topic (listed before) would be the best (and longest) topic to discuss for a 3-5 page essay?
