Slaughtering Americans by the millions was a key objective of the Weather Underground Organization (WUO), which was led during the Vietnam War era by Obama's close Chicagoland friend and Hyde Park neighbor Bill Ayers, among other individuals.

Like the radical left-wing domestic terrorists befriended two decades ago by Barack Hussein Obama, the totalitarian mass murderers of the Islamic State are reportedly determined to kill millions of Americans.

Ayers described the Weatherman philosophy as "Kill all the rich people. Break up their cars and apartments. Bring the revolution home, kill your parents, that's where it's really at."

He was delighted in the 1980s when riot incitement and conspiracy charges against him were thrown out. "Guilty as sin, free as a bird," Ayers gloated. "America is a great country," he said for the first and only time in his life.

Obama infamously began his career in electoral politics at a fundraiser in 1995 in the home of the unrepentant small-c communist terrorist bomber Ayers and his wife Bernardine Dohrn, another former WUO leader.

The Weather Underground plan was ambitious – 25 million Americans deemed unsusceptible to communist brainwashing were to be liquidated – but relatively modest compared to the 500 million souls in the Western world that Islamic State aims to vaporize with nuclear weapons.

As I wrote at FrontPageMag:

German journalist Jürgen Todenhöfer, who spent 10 anxious days living in Islamic State-held Raqqa and Deir ez-Zor in Syria with the jihadists, wants the world to know that the terrorist group is deadly serious about unleashing a "nuclear tsunami" on those who oppose its efforts to create an Islamic caliphate.

According to Todenhöfer, a 75-year-old Christian and pacifist, "[t]his is the largest religious cleansing strategy that has ever been planned in human history."

The West has "no concept of the threat it faces" from the Islamic State (aka ISIS, ISIL, and Daesh) and "dramatically" underestimates the threat posed by the Salafi jihadist army fighting in occupied Syria.

"They are extremely brutal," the former member of the German parliament says.

"Not just head-cutting. I'm talking about the strategy of religious cleansing. That's their official philosophy. They are talking about 500 million people who have to die."

Islamic State fighters are significantly more "dangerous and organized" than people in Western nations assume and "completely sure they will win this fight," the Daily Mail (U.K.) reports the 75-year-old veteran war correspondent saying.

Islamic State "fighters are much smarter and more dangerous than our leaders believe. In the Islamic State, there is an almost palpable enthusiasm and confidence of victory, which I have not seen in many war zones."

On his personal website, Todenhöfer (whose full name can also be spelled Juergen Todenhoefer without the umlauts in German), adds:

I firmly believe that ISIS currently is the largest threat to world peace since the Cold War. We are now paying the price for [former U.S. President] George W. Bush’s act of near-unparalleled folly; the invasion of Iraq. To date, the West remains clueless as to how this threat is to be addressed.

Fresh from conspicuously ignoring in the above statement the role President Obama and former Secretary of State Hillary Clinton played in stirring up Middle Eastern unrest, Todenhöfer says he personally saw volunteer fighters streaming in from around the world to help the Islamic State.

Contrary to common belief, there were many successful and enthusiastic young people from countries like the USA, England, Sweden, Russia, France and Germany. One of them had recently passed his state examination in law and been admitted to the court as a lawyer. Yet, he preferred to fight for the “Islamic State”.

Islamic State warriors "are convinced that their totalitarian faith and demonstrative brutality will help them move mountains," and that their military victories justify their confidence, Todenhöfer writes.

In Mosul, less than 400 ISIS fighters routed [as] many as 25,000 Iraqi soldiers and militias despite their ultra-modern equipment. Within months, the ISIS has conquered a territory larger than Great Britain and dwarfed Al Qaeda.

Todenhöfer's terrifying account comes 20 months after President Obama sat down with the New Yorker and dismissively likened Islamic State to a "jayvee," or junior varsity, team. "If a jayvee team puts on Lakers uniforms that doesn't make them Kobe Bryant," Obama smugly quipped.

In congenital denial about the threat Islamic militancy poses to free nations, Obama said a year ago that "ISIL is not Islamic. No religion condones the killing of innocents, and the vast majority of ISIL's victims have been Muslim."

Obama told the United Nations this week that the Islamic State can be vanquished with tough love and social programs.

"Ideologies are not defeated with guns," the historically illiterate president told U.N. delegates. "They are defeated by better ideas – a more attractive and compelling vision."

Which brings us back to Obama buddy Bill Ayers and the Weather Underground.

We know about the WUO's diabolical plan to exterminate millions of Americans only because of a courageous Ohio man named Larry Grathwohl.

The highly decorated Vietnam War veteran, who died in 2013, risked everything he had to defend the United States of America by taking it upon himself to infiltrate the Weather Underground in the late 1960s.

After fighting Communists abroad, Grathwohl decided to fight them at home. He returned to the U.S. after serving in the U.S. Army’s 101st Airborne Division and set about penetrating the terrorist organization, joining the Weatherman collective in Cincinnati. He rose quickly in the group, aided by his perceived authenticity as a working-class Vietnam vet, unlike the spoiled rich-kid draft resisters who ran the organization.

In his 1976 book, Bringing Down America, which was reissued a few months before he died, Grathwohl summed up why he took the unusual step of joining the Weather Underground in order to undermine it. He feared that these New Left revolutionary communists might actually make headway with their totalitarian program.

"The Weathermen’s government will be one of total control over each individual in the society," he wrote. "In Weathermen terminology, this new society will be 'one people working in total unity.'"

Grathwohl continued: "This means an elimination of all the individual freedoms we are accustomed to having; it was my absolute belief in the freedoms offered by our form of government that drove me to fight the Weathermen in the first place."

Grathwohl's daring descent into the bowels of the anti-American left showed that the subversives of the Weather Underground, which grew out of the Students for a Democratic Society (SDS) splinter group Weatherman, worked with Communist Cuba and the governments of other hostile foreign nations.

Grathwohl attended a kind of Wannsee Conference at which Weather Underground operatives plotted the murder of 25 million Americans. At the Wannsee meeting in 1942, Hitler's cabinet members and senior bureaucrats set in motion the “Final solution to the Jewish question,” which led to the systematic murder of six million Jews.

Grathwohl said the Weathermen put together a plan to exterminate those who resisted their communist revolution. Recounting internal debates within the group, he told an interviewer:

I brought up the subject of what’s going to happen after we take over the government: we become responsible then for administrating [CQ] 250 million people. And there was no answers. No one had given any thought to economics, how you’re going to clothe and feed these people. The only thing that I could get was that they expected that the Cubans and the North Vietnamese and the Chinese and the Russians would all want to occupy different portions of the United States. They also believed that their immediate responsibility would be to protect against what they called the counter revolution and they felt that this counter revolution could best be guarded against by creating and establishing reeducation centers in the Southwest where we would take all the people who needed to be reeducated into the new way of thinking and teach them how things were going to be. I asked, well, what is going to happen to those people that we can’t reeducate that are diehard capitalists and the reply was that they’d have to be eliminated. And when I pursued this further they estimated that they would have to eliminate 25 million people in these reeducation centers. And when I say eliminate I mean kill 25 million people. I want you to imagine sitting in a room with 25 people most of which have graduate degrees from Columbia and other well known educational centers and hear them figuring out the logistics for the elimination of 25 million people and they were dead serious.

One chilling idea WUO leaders entertained was working the enemies of their revolution to death in labor camps, something many so-called progressives today would no doubt favor doing to members of the Tea Party movement.

In its heyday, WUO bombed the Pentagon, the U.S. Capitol, and various other sites of national importance throughout the 1970s. One of its senior leaders, trust fund baby Bill Ayers, now portrayed by the media as an innocuous education reformer, told the New York Times in 2001 that he didn’t regret what he did and he’d likely do it again.

Ayers denies that the Weather Underground's Wannsee Conference ever happened and claims that the WUO never killed anyone. If that's true, it wasn't for lack of trying.

One nail bomb that was supposed to be used to murder U.S. servicemen blew up in the Greenwich Village townhouse where it was being made. As Discover the Networks, the online encyclopedia chronicling the left, reports:

In 1970, Ayers’ then-girlfriend Diana Oughton, along with Weatherman members Terry Robbins and Ted Gold, were killed when a bomb they were constructing exploded unexpectedly. That bomb had been intended for detonation at a dance that was to be attended by hundreds of Army soldiers at Fort Dix, New Jersey. Ayers himself attested that the bomb would have done serious damage, “tearing through windows and walls and, yes, people too.” Notably, Ayers' fingerprints were found at the bomb-making site, along with an assortment of anti-personnel weapons, stabbing implements, C-4 plastic explosive[s], and dozens of Marxist-Leninist publications.

Ayers was obsessed with violence, Grathwohl said. Ayers spearheaded the group's effort "to make plans to select and destroy targets that were symbols of authority. If necessary, we would kidnap government officials for ransom and assassinate others when it was politically expedient."

The Weather Underground also reportedly tried to get its hands on weapons of mass destruction, Pulitzer Prize-winning journalist Jack Anderson reported in his "Washington Merry-Go-Round" column in 1970 ("Weatherman Seeking BW Germs," Washington Post, Nov. 20, 1970).

"An undercover man has tipped off the Customs Bureau that the Weathermen are trying to steal germs from the bacteriological warfare center at Ft. Detrick, Md., to contaminate a city water supply," reported Anderson, a muckraker who was among the most celebrated newspaper columnists of his time. The group's aim was "to incapacitate a population by infection for seven-to-ten days."

The terrorist organization sought "to get the germ cultures, the informant claimed, by blackmailing a homosexual lieutenant at Ft. Detrick."

When Obama was campaigning in 2008, commentator Andrew C. McCarthy III ridiculed Ayers for claiming that the Weathermen never hurt or even tried to hurt anybody.

These savages wanted to kill massively. That they killed only a few people owes to our luck and their incompetence, not design. They and the Democrat politicians who now befriend and serve them can rationalize that all they want. But those are the facts.

McCarthy led the 1995 terrorism prosecution against the "Blind Sheikh," Omar Abdel-Rahman, for orchestrating the deadly 1993 bombing of the World Trade Center.

He knows mass murderers and dangerous sociopaths when he sees them.
