The European Union is an organisation for countries in Europe, so the US could not join. There are over 50 countries in Europe, 28 of which are members of the European Union. There is no reason why the US would even want to join the European Union. It would make no sense for them to do so.
The European Union did not exist in 1952. Instead, the European Steel and Coal Community was created by the countries of Belgium, France, West Germany, Italy, Luxembourg, and the Netherlands. The European Steel and Coal Community morphed into what is known as the European Union today.
What was then known as the European Economic Community, was founded in 1957 by France, West Germany, Italy, Belgium, The Netherlands and Luxembourg. It is now known as the European Union.
