The possibility of a space weather event existed before this EO¹, as did the ability of the government to declare martial law. This EO did not grant any additional powers as regards to martial law, so the contents of this EO change nothing about reasons/legality/probability of martial law. The EO basically puts government departments on notice that they need to pay attention to this and, interesting enough, give the bureaucrats some deadlines to get 'er done!skeeterss0 wrote:basically gives gov. reason to declare martial law.
¹Canada suffered from a significant space weather event in 1989, that brought down part of their electric power grid, so this is not speculative.
