The Weather Underground Organization (WUO), or Weathermen is a leftist terrorist organization now possibly inactive.  Since its inception the Weather Underground identified its fundemental strategic thesis with the Maoist Chinese. In its initial ideological statement, You Don't Need a Weatherman to Know Which Way the Wind Blows, the objective of wealth redistribution was put forward to justify revolutionary violence:
|“||It is the oppressed peoples of the world who have created the wealth of this empire and it is to them that it belongs; the goal of the revolutionary struggle must be the control and use of this wealth in the interests of the oppressed peoples of the world. It is in this context that we must examine the revolutionary struggles in the United States.||”|
According to the traditional Soviet sponsored Leninist model, the proletariat is the main revolutionary force, and national liberation movements become its allies. According to Maoist inspired Weathermen, however, the revolutionary national movements were proletarian revolutions in their own right against the world imperialist class, and provided the leadership in the worldwide anti-imperialist revolution.
Greenwich Village bomb factory
Their ideology was explicitly communist and revolutionary. In one famous incident, several members were killed in the "Greenwich Village Explosion", in which three bomb-makers immolated themselves  preparing for a terrorist attack on Fort Dix. Other members, Cathy Wilkerson and Kathy Boudin, survived and were defended by National Lawyers Guild  members. Kathy Boudin later received a 20-years-to-life sentence for her role in the 1981 Weatherman Nyack, New York Brinks armored truck robbery which resulted in the murders of two policemen and an armored truck security guard. 
At a 1969 "War Council" in Flint, Michigan, spokeswoman Bernardine Dohrn gave her most memorable and notorious speech. Holding her fingers in what became the Weatherman "fork salute," she said of the bloody murders recently committed by the Manson Family in which the pregnant actress Sharon Tate and a Folgers Coffee heiress, and several other inhabitants of a Benedict Canyon mansion were brutally stabbed to death,
|“||Dig it! First they killed those pigs, then they ate dinner in the same room with them. They even shoved a fork into the victim's stomach! Wild!"||”|
Barack Obama and the Weather Underground
In 1995 a cadre of like minded individuals gathered in the home of Weather Underground (WUO) terrorists Bernardine Dohrn and William "Bill" Ayers. According to Dr. Quentin Young, "I can remember being one of a small group of people who came to Bill Ayers' house to learn that Alice Palmer was stepping down from the senate and running for Congress." Dr. Young, a longtime friend of the Ayers' and President Obama, put up the money in 1968 to pay for the office that organized a riot in Chicago during the Democratic National Convention. Carl Davidson of Progressives for Obama was told by Fidel Castro in March 1968 that Castro believed the United States was ready for revolution. Several Students for a Democratic Society (SDS) and WUO cadre trained in Cuba prior to the insurgency. The FBI summarized the situation:
|“||Rarely has any city been threatened all at one time with an invasion of 100 to 200 thousand dissidents - plots to assassinate governmental dignitaries and prominent individuals; intentions to instigate major riots in varied ways; widespread sabotage of communication, transportation and electrical systems- proposals to pour hallucinogenic drugs into the water supply; clandestine shipments of arms and ammunition into the city for use in sniper activities - and myriad forms of guerrilla warfare.||”|
One veteran of the guerrilla warfare training in Cuba was Obama's host, Bernardine Dohrn. Young met with Dohrn after her return,
|“||Bernardine went down there already influenced by Cuba and in a state of romantic anticipation. She was at the top of her thermometer going down. I talked to her, sort of debriefed her, when she came back."||”|
Dr. Young related Illinois State Senator Alice Palmer was choosing then Chicago city councilman Barack Obama as her successor. Palmer once served on the executive board of the U.S. Peace Council, a KGB front organization that actively opposed President Ronald Reagan's defense program. Palmer wrote a report on her visit to Moscow for the 27th Congress of the Communist Party of the Soviet Union (CPSU) published by the CPUSA's People's Daily World. In the twilight of the Soviet regime Palmer wrote, "Like the Reagan administration, the Soviets talk of increasing productivity among workers and curbing waste...but the Soviets' do not link these issues with ruining the living standards of human beings."
Ayers and Dohrn took credit, and have never denied responsibility for a series of terrorist bombings which included the U.S. Capitol, the Pentagon and the State Department. The reopening of a cold case homicide investigation of a San Francisco police officer was urged by the San Francisco Police Officer's Association in March 2009. An FBI informant who infiltrated the WUO and was close to Ayers reported an exchange he had with Ayers about a prospective bombing:
INFORMANT: We'll blow out the Red Barn restaurant. Maybe even kill a few innocent customers — and most of them are black.
AYERS: We can't protect all the innocent people in the world. Some will get killed. Some of us will get killed. We have to accept that fact.
Ayers and Dohrn were not prosecuted because of tainted evidence gathered by the FBI. Assistant Director of the FBI Mark Felt, also known as “Deep Throat” in the Watergate Affair, was prosecuted and convicted for civil rights violations of Jennifer Dohrn, Bernardine’s sister, while tracking the terrorist pair. Ayers boasted in his book that he was "guilty as hell, free as a bird," and Felt was pardoned by President Ronald Reagan who noted Felt followed procedures he believed "essential to keep the Director of the FBI, the Attorney General, and the President of the United States advised of the activities of hostile foreign powers and their collaborators in this country.
Ayers, Dohrn and Barack Obama's relationship went back several years and they were lending their notoriety among radical leftists to launch Obama's career as Palmer's successor. Ayers' and Dohrn's first book written with Jeff Jones, the title Prairie Fire is taken from the sayings of Chairman Mao's Little Red Book,  "a single spark can set a prairie fire"," announces,
|“||we are communist men and women.||”|
Co-author and co-Weather Underground founder Jeff Jones worked for several years with Obama administration Green Czar Van Jones, another self-described communist arrested in the aftermath of a deadly riot. Like Frank Marshall Davis, there is no indication Ayers, Dohrn, Jeff Jones, Dr. Young, Anita Dunn, or other close associates of Obama have renounced their faith in what Allen Weinstein describes as "a murderous and discredited ideology."
Obama was elected to the Illinois State Senate in 1996 and served there for the next eight years.
President Obama is the first person having ties to a known former terrorist to gain control over America's nuclear weapons. Author and blogger Jack Cashill requisitioned a comparison of the writing style of Bill Ayers' 2001 memoir, Fugitive Days, with Barack Obama's earlier 1995 book, Dreams From My Father, and came to the conclusion that Obama's former boss Ayers may have ghostwritten Dreams. Ayers confesses to violent acts, planting bombs, says he has no regrets and feels he "should have done more."

"In assessing the signature of sample passages from Dreams," the experienced analyst found "a very strong match to all of the Ayers samples" that he processed. He did not address the possibility that Ayers had plagiarized from Obama's earlier book. A philosophy professor from England disagreed.
