On September 23, the United Nations Security Council heard directly from leading frontier-AI figures about risks that no company or country can manage alone.

The briefing focused on loss of control, concentrated power and systems advancing faster than institutions, while also showing how the same technology can be used to attack and defend.

The meeting produced no treaty or binding global rules. It marked an institutional shift: frontier AI had moved from technology policy into the Security Council’s peace-and-security debate.

Greenland, Denmark and the United States signed an agreement that expands Arctic defence cooperation while reaffirming Danish sovereignty and Greenlandic self-determination. It still needs parliamentary procedures in Denmark and Greenland before entering into force.

The United States may modernize Pituffik Space Base and propose additional defence areas, but any new area requires mutual agreement. Activity inside agreed areas must respect Greenlandic society, hunting, fishing and cultural traditions to the maximum extent possible.

The agreement has no fixed end date and can be amended only by mutual consent. If Greenland becomes independent, the governments commit to ensuring it remains in, or joins, NATO and assumes the agreement’s obligations.
