Which of the following statements best characterizes the country of North Korea?

Characterizing North Korea involves considering its political, economic, and social context. As of my last knowledge update in January 2022:

North Korea is best characterized as:

• An authoritarian regime led by a single party, the Workers' Party of Korea, with power centralized around the Supreme Leader (as of my last update, Kim Jong-un).
• A closed, isolated country with limited external interactions and controlled access to information.
• A country with a command economy where the government plays a dominant role in economic planning and decision-making.
• A country known for its nuclear program, leading to international tensions and sanctions.
• A nation with a highly regimented society, strict controls on individual freedoms, and limited political pluralism.

It's important to note that circumstances can change, and new developments may have occurred since my last update.
