That's a subtle point. My stance is that their ethical obligation in that regard stops at the border, given that the reason it's a consideration is malicious actors rather than a direct consequence. Otherwise you're letting external, malicious actors hold your population hostage. I don't have numbers for Scandinavia as a whole, but 95% of Norway's population have stated that they will get vaccinated, and we're approaching that number. Antivaxxer disinformation is not a problem that has significant effect here. While it's a tragedy that the USA and others have large populations that are susceptible to propaganda from malignant forces, it's ultimately a matter of US interior politics. It's a whole separate question that not something other countries should shape their politics to conform to. There's very little the international community can do about US poverty, its ridiculously polarized political climate, education system, power imbalances and so on. It's not that I don't care at all; I can see the mathematics of it. But that kind of butterfly effect consideration will quickly lead you down a rabbit hole that prevents you from doing the right thing because someone is holding a gun to a stranger's head.
