I'm doing a history project and i need a narrow subject to focus on. For example i cant do the cold war or nelson madela but something that happened, e.g nelson Mandela and the f.b.i.
WW II has a bunch of smaller activities--Dunkirk, for example.
Vietnam--the Gulf of Tonkin resolution, a small event which ultimately led to the entire US buildup.
The Bay of Pigs under JFK.
