Washington prepares for war (Ad)

While the headlines obsess over overseas conflicts, Washington has been quietly preparing for something much bigger here at home. Emergency powers are being invoked, trillions are being mobilized, and the scale rivals anything we’ve seen since WWII. According to Porter Stansberry and Jeff Brown, a new economic arms race is already underway — one that could reshape markets, redirect capital, and impact billions of lives. They’ve just released an urgent briefing that explains what’s really happening behind the scenes, and which companies are positioned to benefit most.tc pixel
