There are a number of people posting on FR that CW II is coming. I talked to a neighbor yesterday and he just bought several thousand rounds of ammo. I have a good supply of various calibers myself.
CWII is not coming. Our circumstances now don't even remotely resemble circumstances prior to the civil war that started in 1861. You and your neighbors can buy all the guns and ammo you want, it won't do you any good because none of you will ever get to use it.
Who are you going to shoot at? Who is going to lead this so called civil war? Who and where are the rebels?
