The Presidency and The Cold War is a site from the Smithsonian that has videos and online interactives focusing on the U.S. Presidency during the Cold War.
There’s a nice feature called Critical Presidential Decisions that provides audio text for the text. The situation is described briefly, and then the user has various options about how he/she would have responded to the crisis.
The site is accessible to high Intermediate and Advanced English Language Learners.
I’ve placed the link under Our Changing Nation.
