I'm confused as to what relevance Iceland has.
Is that meant to clear up the biggest mystery in Zankyou no Terror? That being why do the Americans sound so weird. Because they're in fact not American but Icelandic?
lol
I'm pretty sure this is not the answer you're looking for, but if it helps, Zankyou no Terror is set in a post-WWII era in which Japan struggles to regain its honor through various conflicts (such as creating atomic bombs). Iceland was neutral during WWII, which, I suppose, may symbolize Sphinx's desire of peace, especially since they were directly affected by these conflicts.
As for the Americans... well, I suppose they just didn't want to take any chances with the potentially harmful Japanese, which may explain the ending. They were pretty much under Five's command for a significant portion of the show (or at least, Five had a lot of say in what happened), and all we really know about her intentions is that she just really, really wanted to beat Nine, and she poured everything she could into doing so. And that's probably why the Americans were acting so strangely.
The anime was tragically beautiful, but I think I could do with a few explanations as well . n .My friend thinks they sound so ridiculous just becuase their voice actors didn't speak english
lol
One last thing that bugs me is why, when nine has the capability to destroy a nuclear reactor with him they decide to shoot twelve in the chest no less and then just leave. They had two copters! They could have killed them both eliminating the chance of him detonating it, instead they took a huge, weird risk of only killing twelve. Makes no sense
