A war of words between Russia and the United States this week brought the tension between the two countries to one of its highest points since the end of the Cold War.
Russian President Vladimir Putin has traded barbs with the White House over Ukraine, harkening to the 40-plus year period in the 20th Century when the two nations were constantly braced for the possibility of nuclear war.
In case you've forgotten -- or weren't born yet -- here are some reminders of how weird life was under the threat of nuclear war between the two world powers, and how some of our most popular cultural touchstones had their start during Cold War years.
1. James Bond
One of the greatest fictional spies in Western culture, James Bond came about under the shadow of the Cold War and the battle against communism, debuting in 1953's Casino Royale.
Bond is a British Secret Service agent battling against criminal entities, and the stories are filled with Soviet spy-types.
2. Space Race Playground Equipment
During the Space Race in the 1950s and 1960s, the U.S. government was intent on getting kids interested in science and space so that they might beat Russia in the space race. Space-themed toys, including rocket-shaped playground equipment and jungle gyms, began popping up all over the country.
3. Duck-and-Cover Drills
The threat of nuclear disaster percolated across the country during the Cold War years, and the government created educational videos and mandates to help students practice taking cover in case of an atomic bomb attack. Students across the U.S. were used to "duck and cover drills," which became almost as common as fire drills during the Cold War years.
4. Air Raid Sirens and Fallout Shelters
The government also used air raid sirens and fallout shelters to help prepare the American public for the possibility of nuclear disasters. Buildings across the U.S. still bear the trademark "Fallout Shelter" signs that showed nearby residents where the closest shelter was to take cover and avoid the dangerous radiation emitted by a nuclear bomb.
5. Germany, Divided
It might be easy to forget when traveling in modern-day Germany, but not too long ago the country was divided and the border heavily guarded. The Berlin Wall divided the city of Berlin and represented a divided country: East Germany was part of Russia's Soviet Bloc while the west was aligned with the U.S. and Europe. The wall stood until 1989.
