Review: Polar War — How US Arctic Preparedness Falters as Ice Retreats

# What this review covers Kenneth R. Rosen's Polar War is based on more than two years of reporting with military units, scientific stations, and Arctic communities. The book focuses on U.S. preparedness as sea ice retreats and geopolitical competition in the Arctic intensifies. The reviewer centers on Rosen's portraits of operational failures, the causes behind them, and the wider strategic implications.

# Concrete examples of failure Rosen uses front-line vignettes to make abstract budget and policy choices visible. Aboard the U.S. icebreaker Healy, routine tasks unravel because equipment is frozen, improvised, or simply absent. When a small boat transfer jammed the off-load release, a petty officer answered "I am a mallet" as he hacked the mechanism with debris. That anecdote is meant to show how crews adapt using makeshift solutions.

# Systemic problems Rosen identifies Rosen traces many of these operational shortfalls to long-term underinvestment and postponed decisions:

• Runways and barracks in Alaska and Greenland show structural problems and inadequate winterization.

• Program faces persistent delays, limiting ice-capable fleet availability.
• Deep-water port infrastructure, storage, and container facilities in Alaska are insufficient to support sustained operations.

He reports medical personnel using improvised setups — like sous vide machines in hardware-store buckets — to keep medications at the right temperature despite the existence of heated medical chests that aren't available or maintained.

# Strategic framing and tradeoffs Rosen argues that the same political logic that delayed climate adaptation decisions also sidelined sustained Arctic investment. For decades, the region was treated as a distant, expensive problem while other theaters received priority. That history, he contends, has left the United States "an Arctic nation that doesn't know how to be an Arctic nation," to quote Captain Krautler of the USCGC Stratton.

The reviewer notes an important counterpoint Rosen acknowledges: maintaining specialized infrastructure in remote, harsh environments forces hard tradeoffs. Some capability gaps may reflect strategic prioritization rather than straight negligence. Still, Rosen's central claim is that the cumulative effect of deferred investments now reduces U.S. effectiveness and creates openings for competitors that are actively expanding Arctic presence.

# Why readers should care Rosen's reporting links everyday failures aboard vessels and at outposts to broader strategic consequences: slower responses, degraded deterrence, and constrained operations in a region undergoing rapid environmental change. The book turns policy debates into concrete scenes that make it easier to assess how ready U.S. forces currently are for increasing Arctic activity.

# Bottom line Polar War uses vivid, ground-level reporting to argue that decades of underinvestment have left U.S. Arctic forces and infrastructure ill-suited to the operating environment and strategic demands now emerging with a melting Arctic. It presents a practical case that decision-makers face choices about where to allocate scarce resources and what capability shortfalls to accept or remedy.
