I should have mentioned that I had, indeed, visited that link. My point is that even there no argument, as such, is presented! Never does he present an argument attempting to demonstrate, using any of the common rules of argumentation, that there is any real link, other than in his imagination, between the UK and US on the one hand and tribes of Jacob on the other. I'm not going to send in for his booklet if I have no reason to suppose that its argumentation is any more persuasive.
I am not opposed to learning that there exists such a convincing argument--indeed, I am predisposed to believing that myself. I am opposed to faulty logic and assumption masquerading as one.
You can also get it in PDF Format right beneath the "Request by Mail" link.
The link was to a 60 something page booklet, but it's freely available on line as either in PDF or HTML.
It will require quite a bit of study of both scripture and history. But it's conclusions are fascinating and illuminating. I believe it, but your mileage may vary. :-)
