17 And I beheld that their mother Gentiles were gathered together upon the waters, and upon the land also, to battle against them.
In the idea I have suggested in verse 16, Satan sees too late that this land has been preserved, not just ignored by the Lord. So now that the Gospel of Jesus Christ has a place to be restored, Satan does all he can to prevent it. So he stirs up the people in the homeland to battle against the settlers, and we have the real reason for fighting the French and Indian War, the Revolutionary War, War of 1812, etc.
