Nuggets from Occult Invasion—Territorial Spirits?

Dawson writes, “The Bible usually identifies an evil spirit by its territory…for example, ‘The prince of the kingdom of Persia’ (Daniel:10:13But the prince of the kingdom of Persia withstood me one and twenty days: but, lo, Michael, one of the chief princes, came to help me; and I remained there with the kings of Persia.
See All...)….” Usually? Here is the one example proponents can find to justify the “territorial spirit” fad. But it doesn’t fit. Daniel was not praying for Persia but for prophetic insight concerning the last days. That insight (being brought by Gabriel) was what this “prince” opposed. Neither Daniel nor Gabriel “bound” this “prince”; nor is there any hint that to do so would have resulted in some spiritual breakthrough for Persia. Were Daniel and Gabriel simply ignorant of today’s new strategies and thus failed to apply them?
