Considering Iceland's strategic position, which had also been noted in WW2, meant the Soviets had to invade the base air at Keflavík and secure the island, but would still face the risk of a counterstrike by the UK's Royal Navy, until the U.S. Marines could arrived and joined the battle along side the small American garrison force.
The volcanic Iceland has many geysers, including Geysir, from which the English word is for the geological entity derived; and thus widespread availability of geothermal power. There are rivers and waterfalls that can be for hydroelectricity.
The sub-polar oceanic climate of Iceland varies between different parts of the island and it's glaciers with, the south coast be warmer, wetter and windier than the north, the Central Highlands and the glaciers are the coldest part of the country and Low-lying inland areas in the north are the most arid. Snowfall in winter is more common in the north than the south, but less in the centre zone. The additional warmth of the North Atlantic Current ensures generally higher annual temperatures than in most places of similar latitude in the rest of the world.
As a fellow Nordic nation, Iceland shares strong cultural and historic ties with its overseas neighbours Denmark and Norway that date back to Viking times. The Icelandic Language is both very closely related and mutually intelligible with both the Faoese language and some Norwegian dialects.
After Soviet invasion of Denmark and/or Operation Northern Norway Iceland and the Fearo Islands would fall. Iceland would be attacked by a Soviet VDV Paratroopers, an amphibious attack and a minor gunboat or two.
The Soviet invasion of Jan Mayen Island would have also soon followed the fall of northern Norway, leading to the capture of the NATO held LORAN-C Station, near Olokin City (which is only actually a small village). There would have been a few Norwegian and NATO troops as security guards, but no major troop numbers since the island is so small.
After capturing the NATO air station at Keflavík and the near by intelligence gathering post, the next goal was the eliminating the SOSUS sonar buoy line in the GIUK gap which would allow the Soviet Navy to surge its submarines into the Atlantic Ocean without being detected and distribute sea mines in the region. The Soviet ships and submarines would then go on to engage and destroy NATO shipping in the North Atlantic..
Eventually the Soviet invasion of Greenland would occur to prevent a Danish government in exile forming, assuming the American air bases had not already secured the island for NATO.
Iceland has the smallest population of any NATO member and is the only one with no standing army, its lightly armed coast guard being in charge of defence. The NATO bases were the only real armed forces the island had.
America had NATO air station at Hofn Air Station, Rockville Air Station and Keflavík International Airport were the only meaningful armed forces on the island. NATO also maintained a joint Icelandic civil and US/UK/Danish run high power military radio mast near Reykjavik from the early 1960s to the early 1980s.
