US Now Biggest Source of Global Uncertainty, Says Ian Bremmer at Davos 2026

• Ian Bremmer, President of Eurasia Group, states the US, not the Middle East, China, or Russia, is driving global uncertainty.
• Donald Trump's return amplifies risks, with Washington's domestic divisions and unilateral foreign policy shaking international foundations.
• Europe feels the shift acutely, questioning collective security, free trade, and rule of law, especially with the Greenland controversy.
• Bremmer warns of a "G-zero" environment globally, lacking clear leadership and stable rules, impacting Venezuela, Ukraine, and China.
• The potential end of NATO is discussed if Trump persists in demanding control of Greenland, a move unpopular and unnecessary for US security.

Why It Matters: Ian Bremmer asserts the US is now the primary driver of global uncertainty due to internal divisions and unilateral policies.
