The Pentagon is pushing to make US military bases able to run for months with zero outside help, a sign officials are genuinely worried about war and cyberattacks hitting home.

• The plan calls for portable nuclear reactors, big battery storage, and mini power grids so bases can cut ties with civilian electricity, plus stockpiles of fuel, weapons, and medical supplies.
• This comes alongside a wave of serious cybersecurity flaws being called "Black October," including a widely used web programming flaw that hit most websites worldwide, and AI tools that now let low-skill hackers pull off attacks once only major governments could manage.
• The UK's prime minister is separately telling citizens to stockpile food and water at home, citing a world where disruptions are becoming more likely.
• The ongoing Iran conflict and the broader proxy war with Russia are raising fears that banks, power companies, and water utilities running outdated systems could be targeted.
• Cuts to US clean energy funding have left the country more exposed on power supply just as this self-sufficiency push ramps up, while China keeps adding grid capacity.

Outlook: Expect more official preparedness warnings and personal stockpiling as the Iran conflict and AI-driven hacking risks continue without any clear government fix in sight.
