Socialism in one country

Socialism in one country is an idea that it's possible to build socialism in a single country without needing a worldwide revolution to achieve it. It means that a country can form a government and economy that puts the needs of the people and their access to resources first, without waiting for help and support from other countries. In this way, people in a single country can work together to create a society and economy that works for everyone.
