If the premise of the articke was "10 Disturbing SHTF Threats that most People Havent Prepared For" then I would agree, but most preppers I talk with have given defense considerations a great deal of thought.
Exactly. In fact, I’d say many preppers have thought too much about defense, or rather, put too much emphasis on peripheral defense issues. They collect tons of tactical gadgets and camouflage outfits and prepare plans for tactical patrols through their backyard, and yet don’t think much about things like garbage disposal.
Not just defending, but also cache-ing and concealment are important to deal with these first five as well.
