NATO Must Shore Up Control of a Key Maritime Chokepoint

Defense One – One of NATO’s geographic advantages—control of the lands around a key maritime chokepoint—may be in peril. For decades, alliance forces have used nearby bases to keep tabs on Russian submarines, surface ships, and aircraft transiting the Greenland-Iceland-United Kingdom, or GIUK, Gap, which consists of a 200-mile stretch of ocean between Greenland and Iceland and a 500-mile gap between Iceland and Scotland. But strong independence movements in Greenland, the Faroe Islands southeast of Iceland, and Scotland could soon jeopardize this position.
