I think he should read up on the solution;
"Now as soon as the thousand years have been ended, Satan will be let loose out of his prison, 8 and he will go out to mislead those nations in the four corners of the earth, Gog and Magog, to gather them together for the war. The number of these is as the sand of the sea. 9 And they advanced over the breadth of the earth and encircled the camp of the holy ones and the beloved city. But fire came down out of heaven and devoured them. 10 And the Devil who was misleading them was hurled into the lake of fire and sulphur, where both the wild beast and the false prophet [already were]; and they will be tormented day and night forever and ever." Rv20:9
