North Korea’s nuclear program: from NPT to constitutional nuclear state

North Korea has developed nuclear weapons and missiles over decades, with intermittent negotiations and international sanctions failing to halt its program.

• 2003: North Korea withdraws from the Nuclear Non-Proliferation Treaty and declares it has nuclear weapons.
• 2006: North Korea conducts its first nuclear test, leading the UN Security Council to impose sanctions.
• 2018: Trump and Kim meet in Singapore, resulting in pledges of denuclearization.
• 2023: North Korea amends its constitution to expand its nuclear force, with Kim Jong Un stating denuclearization is not up for discussion.
