Cuban Missile Crisis
The 1962 Cuban Missile Crisis was a nearly two-week-long period during which a single wrong step could have started a nuclear war in the world. It all began when the US found Soviet-sanctioned missiles in Cuba. The action had violated previous agreements between the two nuclear superpower countries. The next couples of days were very critical for the entire world – the US was planning to either send air raid or perhaps an invasion of Cuba to destroy the missiles. Both could have surely ignited a nuclear war. Fortunately, both the countries were able to strike a last-minute deal and everything got back to normal.
