The data point in Iceland about a military base being located here is not correct anymore. There used to be a base at/around Keflavík International Airport, built in WW2 but closed in 2006. Iceland is part of NATO though so there are usually one or two jets from NATO at the airport doing their things. But there’s no base there anymore.
Most of the base has been turned into a village on its own, a movie studio, concert venue, university, etc…
complete abolishment of animal agriculture is not done overnight with in one fell swoop. It’s done with small changes here and there. Slowly forging a new culture where it is considered worse and worse to treat animals badly. (and what counts as animal abuse will start covering more and more things). Slowly changing the norm. Same goes for privacy, user rights, etc. There are of course some key moments, watershed moments, legislations (GDPR for example), but those had a long journey of tiny steps all over the world before they came into being. Sort of like tectonic plates building up tension over tens, hundreds, thousands of years before they snap into place in one huge earthquake
