Okay, how does one write about an entire nation? Not just characters within a nation, but the entire nation's progress through history and so on. For example, if I were to write a story about the Soviet Union from 1920 to 2064, I would need a way to characterize the entire nation if that's what the focus of the story is, which in this example it is. But how does one do this? Tons of characters describing each part of it? The leaders? How? Remember I'm asking about how to write a story where the nation is the focus of it, not just the setting that supports the characters, although this is perhaps a time where the setting is a character rules applies the most.
