It was also the strategy of the Chinese People's Liberation Army in the 1940s, the Viet Cong in the 1950s to 1975, Castro's rebels in the 1950s, the various groups in Yugoslavia in the 1940s, the "anarchists" in Europe and Russia in the 1800s...even the "Children of Israel" during their conquest of Israel after they left Egypt and the revolts of the Maccabees and the Zealots.

But remember too what happened to these: China and Vietnam are effectively capitalist countries under single-party rule, Yugoslavia split and split again with faction against faction, Europe crushed the revolts of 1848 (and Britain finally gave up on most of Ireland in 1921), Russia collapsed back in the capitalism but pretty much silences any dissent, Israel was conquered over and over, the Maccabees were crushed by the Romans and the Zealots died at Masada.

That's leaving out things like the massacre at Béziers, St. Bartholomew's Day, the Peasant's Revolt, Gnadenhutten, the September Massacres, Anatolia, Mountain Meadows, Croke Park, Amritsar, Bath School,        Ciénaga...and the list goes on and on and on. (NB: I left out ones related to war, but rumors of war are included and I trust I was international in scope.)

I would say that 95% of the "survivalists" in the US, unlike Daesh, have no experience of war and are talking out of their rectums.
