See “whelps of Tarshish”.
I googled up a lot of prophecy websites when I put in "whelps of Tarshish" but none of them went by that name or title. However, I did find an interesting and somewhat convincing article on the same subject that makes the claim that the US and other former British colonies are modern day versions of the merchants of Tarshish to which Ezekial referred in his prophetic message in chapters 38 and 39.
The URL for the article is http://www.rapturealert.com/americainbibleprophecy2.html if anyone is interested. I tied to create a link to it but for some unknown reason the address won't link.
