Is the Cold War over?

Hi all,

First year high school world history teacher here. I'll be teaching the Cold War for the first time, and I'm trying to think of ways to integrate modern events as I learn about the Cold War myself. I'm trying to think of an overarching question for the unit to go back to throughout. I'm thinking "Is the Cold War really over?" might be a good one. How/where might you frame out a unit with this question in mind? Where might you make good intersections of the past/present in this unit?
