Is America at war in cyberspace? In the face of increasingly brazen cyber attacks against our country, the Obama administration established the first military command devoted to cyberspace, U.S. Cyber Command, in 2010. And the Pentagon has issued a new declaratory policy in which the United States announced that it reserves the right to respond to cyberattacks with conventional weapons. It sounds a lot like war. But is it?
Today, America is most certainly engaged in what amounts to a cyber “cold war.” We face a daily barrage of low-level “tactical” strikes in which foreign adversaries attack our computer networks, often using proxies in cyberspace — much as the United States and the Soviet Union engaged in low-level combat using proxies in Africa and Latin America during the Cold War of the 20th century. In some cases, these attacks escalate into what our military calls operational-level engagements — decisive attacks or incidents that gain front-page attention in the news (such as the Stuxnet virus that attacked Iran’s nuclear program) but do not significantly alter the daily lives of Americans.
