You've pretty much hit on the goal of the book - that there were a lot more military actions than popular history likes to remember. For Norway, it starts with the Battle of Bergen (1665) - which was while the Danes controlled Norway, but is today Norwegian territory. Continues through various naval encounters during the Napoleonic wars, and into attacks on german-held Norwegian territories during WW2 - ending with 1st Airborne landing at Oslo and Stavenger. While very few of these are actually actions against Norway, they are on what is today Norwegian soil, which is the general theme of the book. Chile is similar, in that while there's very little against Chile as a nation, there's plenty of attacks against the Spanish territory that became Chile, starting with the sacking of Valparaiso in 1578, and ending with british fighting with chile to establish their independence from Spain. The general theme of the book isn't "we've attacked every country on this list" - it's more that if you put a pin on the map for every british military action listed through the book, a good 90% of today's countries will find a pin within their territory.
