Imagine if this happened today: Hundreds of young Americans—white, black, and Hispanic—disappear from their everyday lives and secretly form urban guerrilla groups. Dedicated to confronting the government and righting society’s wrongs, they smuggle bombs into skyscrapers and federal buildings and detonate them from coast to coast. They strike inside the Pentagon, inside the U.S. Capitol, at a courthouse in Boston, at dozens of multinational corporations, at a Wall Street restaurant packed with lunchtime diners. People die. They rob banks, dozens of them, launch raids on National Guard arsenals, and assassinate policemen, in New York, in San Francisco, in Atlanta. There are deadly shoot-outs and daring jailbreaks, illegal government break-ins and a scandal in Washington….

In fact, the most startling thing about the 1970s-era underground is how thoroughly it has been forgotten. “People always ask why I did what I did, and I tell them I was a soldier in a war,” recalls a heralded black militant named Sekou Odinga, who remained underground from 1969 until his capture in 1981. “And they always say, ‘What war?’”…

“People have completely forgotten that in 1972 we had over nineteen hundred domestic bombings in the United States,” notes a retired FBI agent, Max Noel. “People don’t want to listen to that. They can’t believe it. One bombing now and everyone gets excited. In 1972? It was every day. Buildings getting bombed, policemen getting killed. It was commonplace.”
