And on top of that, the range of a Trident missile- at least as far as is available in the public domain - doesn't exactly require an SSBN to go anywhere near Argentina. Indeed, what we might call the 'Wikipedia Stated Range' suggests that it wouldn't need to be anywhere near Ascension Island (even the USN website concedes the fact that it has a range of over 4,000 nm).
Edit - beaten to it!
