The second movie is all about spies, which means there was a Cold War, and if there was a Cold War, there was a Russia, and if there was a Russia, there was a Stalin and a Lenin, which means there were communists, and eventually a Red Scare and a McCarthy, which means there was a nuclear scare and, naturally, nuclear weapons.

This rabbit hole goes much deeper than Pixar intended.
