The US Department of Defense has prepared for all major military bases (including in Europe and the US) to be able to operate for 90 days without external support - without civilian power grids, global supply chains, without external fuel and water. The initiative, reported in documents reviewed by Fox News Digital, involves the use of portable nuclear reactors, large-scale energy storage systems and microgrids that can completely disconnect sites from the civilian power grid. Strategic stockpiles of ammunition, fuel, critical minerals and medical supplies will be established to meet the needs of the war. Civilian factories have already been identified that can be repurposed for military production in the event of a crisis. The Pentagon's chief press secretary, Sean Parnell, stated bluntly: “Energy is now a weapon. Without power, you lose communications, water supply, logistics, production lines and even basic military command structures."
