- U.S. and South Korea reached a late‑July 2025 agreement where Seoul will invest $350 billion in the United States and Washington cut tariffs to 15 %.
- President Trump approved South Korea’s nuclear‑powered submarine construction project at the October 2025 U.S.–South Korean summit.
- U.S. support for South Korea’s nuclear submarine capability is framed as a new military option against Russia‑North Korea cooperation.
- Choong‑Koo Lee previously argued in 2025 that the United States and South Korea must jointly weaken the Moscow‑Pyongyang military bond.
- Second Trump administration spent early 2025 readjusting trade and defense relations before tackling the Russian‑North Korean challenge.
Why it matters: South Korea secures a $350 billion investment pipeline and a nuclear‑submarine fleet, strengthening its defense posture and giving the U.S. leverage against Russia‑North Korea aggression, while the tariff cut pressures domestic manufacturers.
