Going by the geographical territory allotments in the book of jubilees the southern part of the US is hamitic territory and the northern is japhetic territory Noah set up a curse for his descendants if one group or another they violated the arrangements hence the us civil war.

The logical thing if japhetic Europeans are to secede is to concentrate in the north, annex Canada and let the minorities to their own devices in the south.
