For me the height of the Cold War was the first Nuclear Test by the Soviet Union on the 29th of August 1949.
This was also probably the start of the 'cold-war' itself.
Before the Soviet Union has tested a live Nuclear Weapon, the United States was flexing it's muscles all over the world based on it's economic and military might.
However, the Soviet Nukes proved that there was another player on the global scene with the same weapons as the United States.
Subsequently Soviet Union couldn't, and in effect did, challenge America's dominance in every corned of the world for the next 40 years.
For me, this precise moment was more important than the 'Cuban Crisis'
Voting rights I believe were restricted in that only one party the Socialist party was allowed. Some socialist countries at least where power was obtained by revolution in the world, like the Soviet Union or in Cuba had/have a one party system but still have democratic votes for various things, whereas more recently, socialist governments have come to power through the ballot box in countries like Venezuela or Bolivia.
D.. its when metal work was getting big and tools were an outcome.
