Key Highlights:

  • NATO weakening may:
    • Undermine rules-based international order
    • Increase regional conflicts and instability
• Europe’s Strategic Autonomy
  • Push towards EU-led defense initiatives.
  • Reduced dependency on U.S. could reshape transatlantic relations.
• Implications for India
  • Increased instability in West Asia and Europe may affect:
    • Energy security (oil routes)
    • Geopolitical balancing (India-U.S.-Russia relations)
• Isolationism vs Global Leadership
  • U.S. policy dilemma between:
    • Domestic priorities (America First)
