The French judge Nicolas Guillou knows exactly how deep Europe’s dependence on US tech is. Guillou and his colleagues at the international criminal court are under US sanctions. They can no longer use e-commerce, book hotels online or hire a car. Their home smart devices ignore them. Credit cards from European banks no longer function, because Europe has still not developed its own EU-wide payments system, so most electronic purchases go through Visa and Mastercard. Converting euros to foreign currencies is extraordinarily difficult because everything passes through dollars. Living in Europe is no protection against Donald Trump bricking your digital life.

This dependence is not limited to mod-cons. Last year, the chairman of the Danish parliament’s defence committee said that he regretted his part in Denmark’s decision to buy US-made F-35 fighter jets: “I can easily imagine a situation where the USA will demand Greenland from Denmark and will threaten to deactivate our weapons and let Russia attack us when we refuse. Buying American weapons is a security risk that we can not run.” He is not alone. Spain has abandoned plans to buy F-35s.

Perhaps the danger should have been clear a decade ago when it was revealed that US spies routinely record the phone calls of millions of Europeans and bug the phones of European leaders. But across Europe, governments, militaries, businesses, doctors, professors and teenagers alike continued to trust US technology. Sensitive state policies are drafted in Microsoft software.
