There is a fairly unremarkable office building in Arlington, Virginia. If you drove past it tomorrow, you probably wouldn’t even notice it. No security gates. No giant corporate logo. Just another nonprofit office tucked between apartment blocks and office parks outside Washington D.C. Inside that building is an organisation called the Atlas Network. Officially, it’s a charitable nonprofit that supports independent think tanks around the world. But over the last forty years, this one organisation has quietly helped build a network stretching across more than one hundred countries, trained thousands of political activists and policy experts, connected them with billionaire donors, and celebrated governments implementing its ideas. Most people have never heard of it. Maybe that’s exactly why it became so influential.
