On March 1, 1971 the United States Capitol is bombed. WUO called ahead stating that this was in protest of Nixon’s resent bombing of Laos. Below is ABC’s reaction to the bombing on the morning news in 1971.

There were three California bombings, two of which WUO claimed credit for on August 28, 1971. The State Department of Corrections offices in Sacramento and San Francisco were both attacked with a corresponding letter from The WU. The third blast that happened in San Mateo was under investigation and no conclusion was come to in deciding if it was related or not.

On May 19, 1972 WUO took credit for the bombing of The Pentagon, which was according to New York Times‘ article “in retaliation for the U.S. bombing raid in Hanoi.” The date was chosen for it being Ho Chi Minh’s birthday. WUO called in before hand and gave them less than an hours notice to evacuate the building.
