U.S. states and cities are breaking with the federal government and signing onto an international pledge aimed at making cyberspace safer. Virginia, Colorado and Washington state have all endorsed the Paris Call, which was first boosted last year by French President Emmanuel Macron and which commits members to combatting major cyberattacks, digital theft of intellectual property and foreign election interference. City governments in Louisville, San Jose and Huntington, W.Va., have also joined. The Trump administration, meanwhile, is still refusing to endorse the pledge — even though it was approved by 74 other nations including our closest allies in Britain, Canada, Australia and New Zealand. The move is another way that cities and states are breaking with the Trump administration. Others have done so on issues ranging from climate change, privacy to immigrant rights. It also underscores how states and localities, which have been pelted with costly ransomware attacks and struggled to protect their elections against highly sophisticated Russian hackers in recent years, are increasingly viewing cybersecurity as an existential threat. “It’s a problem that’s facing us and I really don’t give a flip whether a governor or a president is addressing it,” Huntington, W.Va., Mayor Stephen T. Williams told me. “I’m going to find people on common ground and we’re going to move forward and make our case. If the states and federal government want to come along, that’s fine, but, if not, we’ve got our own voice.”
