Trump's obsession with Greenland has been easy to mock, but Rana Foroohar's analysis in the Guardian — timed to the release of her book Sea Change — argues the instinct is sound even if the execution is characteristically reckless. The September 2025 US-Denmark agreement expanded American troop presence on the island without the annexation Trump theatrically floated, but the underlying logic tracks: Greenland sits at the intersection of Arctic shipping routes, rare-earth mineral deposits, and missile-defense geometry that the Pentagon has quietly prioritized since the Cold War. The numbers behind the Arctic competition are stark. China declared itself a "near-Arctic state" in 2018 and has since tripled its shipbuilding capacity relative to the US. In 2025, Chinese yards produced more than 1,000 ocean-going vessels; the US produced 10. A Chinese shipping company, Sea Legend, launched a weekly trans-polar commercial route in August, claiming to cut the 40-day Europe-Asia voyage in half — an attractive proposition while Houthi attacks continue to threaten Red Sea transit. The US, which ranked first in global shipbuilding capacity in 1975, now produces less than 1% of the world's commercial vessels. Greenland's independence aspirations — targeted for 2033 — add a layer of urgency. US officials, including special envoy Jeff Landry, have argued that an independent Greenland would be more vulnerable to Chinese and Russian influence campaigns. The administration frames expanded presence as facilitating "deployment of advanced missile defense systems" and crowding out adversarial influence, though Foroohar notes no explicit Chinese or Russian security threats exist on the island today. Climate change is the structural accelerant. Melting Arctic ice has unlocked resource extraction possibilities — the seabed holds gas, oil, and rare-earth minerals that remain largely unclaimed — and opened shipping lanes that were physically impossible a generation ago. Russia is already routing energy transit through Arctic waters to bypass global chokepoints. Both Russia and China have conducted military drills near US territorial waters off Alaska. The icebreaker gap is a useful proxy for the broader industrial deficit. The US has minimal icebreaker capacity and has only recently begun a joint production program with Finland, endorsed by both Biden and Trump. But building ships requires shipyards, and shipyards require an industrial base that decades of offshoring have hollowed out. Bipartisan industrial policy — chip manufacturing, shipbuilding — is now aimed at closing this gap, though Foroohar notes the rhetoric is often "couched with xenophobic, anti-China" framing rather than honest structural diagnosis. Foroohar's core argument is that Trump's limbic read on Greenland's importance is correct, but his approach — coercive, ego-driven, alliance-destroying — undermines the very relationships the US needs to secure the Arctic. Shared supply chains, security agreements, and trade pathways with Europe are force multipliers, not concessions. The US-Denmark deal suggests the system can produce reasonable outcomes despite the president's maximalist posturing, but the broader industrial and diplomatic deficits remain unresolved. The piece is fundamentally an argument about the end of the neoliberal era: globalization created wealth but also the industrial hollowing and inequality that now leave the US short of ships, icebreakers, and manufacturing capacity precisely when geography demands them. Whether the pendulum swing toward industrial policy produces results — or just rhetoric — will determine whether the Arctic becomes a US strategic asset or a vulnerability.
