In Washington, President Trump’s wall (or lack thereof) seems to be the talk of the town. But the U.S. should have a different national security priority at the top of its list: cybersecurity.

On Tuesday, the New York Times reported that security group Area 1 had uncovered a long-running hacking campaign targeting, among others, the European Union’s network of secure diplomatic cables. That breach, which had been going on for three years, resembles other hacks carried out by China’s People’s Liberation Army and comes on the heels of revelations that China was responsible for hacking data held by Marriott, the federal Office of Personnel Management, and insurance companies.
