John Lukacs Analyses on Global Affairs: 2026/3.The Transformation of Stability in the South Korea–U.S. Alliance and Its Geopolitical Recalibration (1945–2026)

We are pleased to present the 3th issue of 2026 of John Lukacs Analyses on Global Affairs is out: 2026/3. The Transformation of Stability in the South Korea–U.S. Alliance and Its Geopolitical Recalibration (1945–2026)

 Key insights from this analysis include:

  • The South Korea–U.S. alliance has evolved from a military relationship into a complex security, industrial, and technological partnership, increasingly shaped by transactional logic under the second Trump administration.
  •  “Sovereignty trade” and large-scale industrial investments (e.g., MASGA) are fostering deep integration and enhancing South Korea’s strategic weight.
  • Through increased defense spending and burden-sharing, South Korea is not only a beneficiary but also an active contributor to U.S. interests.
  • Seoul functions both as a deterrence platform against North Korea and as a key actor in Indo-Pacific cooperation.
  •  Alliance status is increasingly contingent on economic and technological contributions, creating new pressures for adaptation.
  • Traditional alliances are gradually transforming into hybrid systems complemented by economic and industrial integration.
  • Competition among allies is intensifying, with economic and technological performance increasingly shaping influence and room for maneuver.
