Eden, how you doing man?
Actually, I'm referencing the Roman 'iron' system which came into Europe and permuted into the nation-state system we call the 'West' today.
The figurative 'iron and clay'.
This 'empire' is plainly referenced in Daniel 2, and 7.
Not to be confused with a spurious framework similar to the Daniel 11 UK-KoTN / US-KoTS conception I know you are familiar with.
(which, on the surface, is clearly referencing Ptolemy and Selecus -whereby Robert King reads the US-UK dichotomy into)
