“Observing U.S. and European operations in the far north, he finds that Nordic troops are much more agile and well-prepared for high latitudes than their American counterparts.
In fact, Rosen gets to compare these forces side-by-side when he follows a Norwegian ship on the way to a planned rendezvous with the USCGS Healy, the U.S. Coast Guard’s only Arctic-specific icebreaker. When the two ships meet, they are suddenly buzzed by a Russian helicopter. The Americans are “visibly unnerved,” Rosen notes. The Norwegians, on the other hand, dryly comment about how they do the same to Russians all the time.
An important lesson is that experience, rather than flashy equipment, makes or breaks a polar army. The cold quickly kills people and destroys machines. Snow does not behave like sand when building fortifications. Cross-country skis are faster than snowshoes. Sunburn is a surprisingly common problem despite the cold. Hooks and ropes have to be carefully maintained. Wind and weather at sea can change unpredictably. Even routine, peacetime shipboardings can be deadly.
The book argues that Europe’s comparative advantage in the Arctic can make NATO worthwhile for the U.S., by reducing the need for an American military buildup up there.

Most people in Greenland are Inuit, members of the same culture that much of northern Canada and coastal Alaska belong to. For centuries, they chafed under Danish colonial rule. Now they enjoy considerable self-rule within Denmark and are deciding whether to pursue independence.
Polls show that most Greenlanders support independence in theory but don’t necessarily want to break away at the moment. The fact that Danish taxpayers pay for half of the Greenlandic government budget is an obvious, widely known barrier to independence. So is the potential loss of the mobility and export markets that European Union membership provides.”
