Former communist countries have been left out of the European Union.

This statement is not entirely accurate. Several former communist countries have joined the European Union since its inception. For example, countries like Poland, Hungary, Czech Republic, Slovakia, Romania, Bulgaria, and others have become EU members in the early 2000s. These countries have undergone significant political, economic, and social reforms to align with EU standards and requirements.

However, it is true that not all former communist countries have joined the EU. Some countries such as Belarus and Russia have not become EU members due to various reasons, including political differences, human rights issues, and geopolitical considerations.

Overall, the EU has shown a willingness to integrate former communist countries into its structures, provided they meet the necessary criteria and obligations set by the EU.
