Sure, there are disasters happening around the world -- just look at Syria! Look at ISIS-controlled territories! But the world envisioned in most TEOTWAWKI planning resembles Walking Dead more than any sort of known historical situation.

I have attempted to start some discussions with survivalists about how they'd fare in actual historical situations. Some of the worst ones include war, completely corrupt and depraved governments, and natural and man-made disasters happening at the same time. In other words, you're caught between forces that you cannot possibly fight. Alas, they don't understand this. They're thinking in an innocent, American way: TEOTWAWKI means a return to the frontier days, with threats from small, dangerous roving bands of desperadoes. The military, if it survives in some form, is "probably on our side." So mainly you need to homestead, and have an ample supply of ammo. For them, TEOTWAWKI is a version of the wild west.

Maybe TEOTWAWKI is totally different from the disaster zones and war zones around the world, but to me, if you cannot survive ISIS, then you don't have a good shot at surviving something even worse.
