Toshio Okada, co-founder of Gainax and author of such books as Introduction to Otakuology and Is World Conquest Possible?, recently took to his official Youtube channel to offer his thoughts on Hajime Isayama's Attack on Titan manga and TV anime, specifically the most efficient way to defend a human city from hordes of cannibalistic giants.

The thrust of Okada's argument is that rather than building an enormous wall surrounding the city (which the Colossal Titan can easily kick holes in), the humans ought to instead dig a gigantic moat around the perimeter so that the landscape itself serves as an impenetrable embankment against Titan-invasion.
