How many battery pack electrical supplies are sold on fears of an EMP event? I think our power supply is more likely to be taken down by sleeper cells placed here by nations that we have militarily or financially bullied over the years. Lat's say that Netanyahoo suckers the Donald into his 40 year old dream of attacking Iran. How many saboteurs would it take to cripple our grid? Are our FBI and other internal security forces competent enough to deter such, given that there may be 30 million+ illegal aliens in the USA and that our security forces focus has been directed at White/Christian nationalists the last 4 years? Life would be unpleasant with a widescale disruption of our grid. Given the manpower and material resources that it takes to restore power in a locale after a hurricane or other weather event, I suspect that we'd have a lot of people forced to live a 19th century existence but without the material or intellectual wherewithal.

America is skating on thin ice.
