And how is the rest of the world?
That's a good question. The only direct mentions about the rest of the world that I remember is a failed escape attempt to Canada and a commander having the protagonist (Offred) listen to a brief message from Radio Free America stationed in Cuba.
I'm not quite sure what the rest of the world would be like. The US economy and investments would hit rock bottom, hurting South America and other regions. The UN would probably be moved, or put on pause. The Soviets would probably take more risks or invade a neighbor. Anyone else have some good ideas?
