The Gist
The author argues that Marco Rubio's diplomacy in Panama, Greenland and Iceland is keeping China away from key shipping routes and giving the US a lasting advantage. The Greenland deal and the Panama canal outcome are presented as proof, even though China isn't yet in Greenland, because Arctic routes will matter more as ice melts. The author credits skilled diplomacy rather than Trump's earlier threats to seize Greenland.
Conclusion
Secretary of State Rubio's diplomatic campaign across Panama, Greenland and Iceland is a significant success that boxes out China, protects US access and interests in critical sea lanes, and establishes a long-term American strategic advantage.
Premises
- China seeks to replace the US as the leading global superpower, and a key part of its strategy is securing critical sea lanes, which give leverage over trade, resources and power projection.
- Melting ice is opening Arctic shipping routes, creating new sea lanes and choke points that will shape global shipping and military posturing for decades, so Chinese absence from Greenland today does not make the deal unnecessary.
- The Greenland agreement with Denmark lets the US block non-NATO commercial and military presence, screen foreign investment in critical sectors, and gain overflight, missile defense and undersea access. It respects Greenland's sovereignty and remains in force in perpetuity, even if Greenland becomes independent.
- In Panama, after Rubio's discussions, a Panamanian court voided the contract under which a Chinese-linked company operated the canal's container terminals, reversing incremental Chinese commercial expansion.
- In Iceland, Rubio reaffirmed the High North's importance for monitoring adversaries and opened negotiations on a possible expanded US presence, conditional on Icelandic consent.
- The successes came through patient diplomacy, not Trump's threats of force against Greenland, which caused NATO panic, market declines and domestic opposition. Progress began only after the threats stopped.
Assumptions
- Control of or influence over sea lanes and choke points is decisive for global power, so denying China such influence advances US security.
- Chinese commercial investment in strategic infrastructure is a vehicle for strategic and military leverage, not merely economic activity.
- Preemptive agreements are worthwhile even without a current Chinese presence, because future threats are foreseeable.
- The Panamanian court ruling and the Greenland deal resulted from Rubio's diplomacy rather than from independent factors.
- A deal that is legally permanent and honors sovereignty will remain politically durable and acceptable to Greenland and Denmark.
- Russia and China are the primary adversaries that justify strengthening US positions in the Arctic and North Atlantic.
