Yes. We usually call it an invading army.
It really could be a side effect of the ISIS mode of attacking a city. Give us your women and children, and we’ll let you go.
In this case, the invasion isn’t even been orchestrated so much by men, as by Satan.
And a potent counter attack to a Satanic attack like this... please hear me out... might be gospel squads. Evangelize those folks (if they aren’t already clearly personally in allegiance to Jesus).
To bring to God what had been in Satan’s hands, is the worst attack you can mount upon Satan. And on an earthly plane, they might be motivated to be “part of the solution.” Islam sold them out. Let’s show them that Christianity won’t.
