Amid the ravages of economic depression, Germans in the early 1930s were pulled to political extremes both left and right. Then, in the spring of 1933, Germany turned itself inside out, from a deeply divided republic into a one-party dictatorship.

In 1945, the Soviet Union controlled half of Europe and was a founding member of the United Nations. By 1991, it had an army four million strong, 5,000 nuclear-tipped missiles, and was the second biggest producer of oil in the world. But soon afterward, the union sank into an economic crisis and was torn apart by nationalist separatism. Its collapse was one of the seismic shifts of the 20th century.

For decades, under cover of classification levels and non-disclosure agreements, the United States government became the world’s dominant hoarder of zero days.
