Overnight, Seymour Hersh published How America Took Out The Nord Stream Pipeline. Here are the key points.

The explosives were allegedly planted months earlier, during a mid-summer NATO exercise:

Last June, the Navy divers, operating under the cover of a widely publicized mid-summer NATO exercise known as BALTOPS 22, planted the remotely triggered explosives that, three months later, destroyed three of the four Nord Stream pipelines, according to a source with direct knowledge of the operational planning.

Planning for the operation began months prior to the war in the last quarter of 2021, and Navy divers were used in order to avoid Congressional oversight and the possibility of leaking to the press:

Biden’s decision to sabotage the pipelines came after more than nine months of highly secret back and forth debate inside Washington’s national security community about how to best achieve that goal. For much of that time, the issue was not whether to do the mission, but how to get it done with no overt clue as to who was responsible.

There was a vital bureaucratic reason for relying on the graduates of the center’s hardcore diving school in Panama City. The divers were Navy only, and not members of America’s Special Operations Command, whose covert operations must be reported to Congress and briefed in advance to the Senate and House leadership—the so-called Gang of Eight. The Biden Administration was doing everything possible to avoid leaks as the planning took place late in 2021 and into the first months of 2022.

Both Nord Stream 1 and 2 were a political and strategic threat to NATO:

America’s political fears were real: Putin would now have an additional and much-needed major source of income, and Germany and the rest of Western Europe would become addicted to low-cost natural gas supplied by Russia—while diminishing European reliance on America. In fact, that’s exactly what happened. Many Germans saw Nord Stream 1 as part of the deliverance of former Chancellor Willy Brandt’s famed Ostpolitik theory, which would enable postwar Germany to rehabilitate itself and other European nations destroyed in World War II by, among other initiatives, utilizing cheap Russian gas to fuel a prosperous Western European market and trading economy.

Nord Stream 1 was dangerous enough, in the view of NATO and Washington, but Nord Stream 2, whose construction was completed in September of 2021, would, if approved by German regulators, double the amount of cheap gas that would be available to Germany and Western Europe. The second pipeline also would provide enough gas for more than 50 percent of Germany’s annual consumption. Tensions were constantly escalating between Russia and NATO, backed by the aggressive foreign policy of the Biden Administration.

Events in the latter half of 2021 made some sort of decision inevitable:

The administration was floundering, despite getting a reprieve on the crisis in mid-November, when Germany’s energy regulators suspended approval of the second Nord Stream pipeline. Natural gas prices surged 8% within days, amid growing fears in Germany and Europe that the pipeline suspension and the growing possibility of a war between Russia and Ukraine would lead to a very much unwanted cold winter. It was not clear to Washington just where Olaf Scholz, Germany’s newly appointed chancellor, stood. Months earlier, after the fall of Afghanistan, Scholtz had publicly endorsed French President Emmanuel Macron’s call for a more autonomous European foreign policy in a speech in Prague—clearly suggesting less reliance on Washington and its mercurial actions.

Throughout all of this, Russian troops had been steadily and ominously building up on the borders of Ukraine, and by the end of December more than 100,000 soldiers were in position to strike from Belarus and Crimea. Alarm was growing in Washington, including an assessment from Blinken that those troop numbers could be “doubled in short order.”

The administration’s attention once again was focused on Nord Stream. As long as Europe remained dependent on the pipelines for cheap natural gas, Washington was afraid that countries like Germany would be reluctant to supply Ukraine with the money and weapons it needed to defeat Russia.

A number of ways of destroying the pipelines were allegedly discussed before finally settling on diving teams:

Over the next several meetings, the participants debated options for an attack. The Navy proposed using a newly commissioned submarine to assault the pipeline directly. The Air Force discussed dropping bombs with delayed fuses that could be set off remotely. The CIA argued that whatever was done, it would have to be covert. Everyone involved understood the stakes. “This is not kiddie stuff,” the source said. If the attack were traceable to the United States, “It’s an act of war.”

At the time, the CIA was directed by William Burns, a mild-mannered former ambassador to Russia who had served as deputy secretary of state in the Obama Administration. Burns quickly authorized an Agency working group whose ad hoc members included—by chance—someone who was familiar with the capabilities of the Navy’s deep-sea divers in Panama City. Over the next few weeks, members of the CIA’s working group began to craft a plan for a covert operation that would use deep-sea divers to trigger an explosion along the pipeline.

German Chancellor Scholz was informed in early February 2022 and both Biden and Nuland indicated that as much in the press conference that followed and weeks earlier, respectively:

Nevertheless, in early 2022, the CIA working group reported back to Sullivan’s interagency group: “We have a way to blow up the pipelines.”

What came next was stunning. On February 7, less than three weeks before the seemingly inevitable Russian invasion of Ukraine, Biden met in his White House office with German Chancellor Olaf Scholz, who, after some wobbling, was now firmly on the American team. At the press briefing that followed, Biden defiantly said, “If Russia invades . . . there will be no longer a Nord Stream 2. We will bring an end to it.”

Twenty days earlier, Undersecretary Nuland had delivered essentially the same message at a State Department briefing, with little press coverage. “I want to be very clear to you today,” she said in response to a question. “If Russia invades Ukraine, one way or another Nord Stream 2 will not move forward.”

The operation was allegedly based in Norway:

Back in Washington, planners knew they had to go to Norway. “They hated the Russians, and the Norwegian navy was full of superb sailors and divers who had generations of experience in highly profitable deep-sea oil and gas exploration,” the source said. They also could be trusted to keep the mission secret. (The Norwegians may have had other interests as well. The destruction of Nord Stream—if the Americans could pull it off—would allow Norway to sell vastly more of its own natural gas to Europe.)

The Norwegian Navy identified the most efficient location for the attack:

The Norwegian navy was quick to find the right spot, in the shallow waters of the Baltic sea a few miles off Denmark’s Bornholm Island. The pipelines ran more than a mile apart along a seafloor that was only 260 feet deep. That would be well within the range of the divers, who, operating from a Norwegian Alta class mine hunter, would dive with a mixture of oxygen, nitrogen and helium streaming from their tanks, and plant shaped C4 charges on the four pipelines with concrete protective covers. It would be tedious, time consuming and dangerous work, but the waters off Bornholm had another advantage: there were no major tidal currents, which would have made the task of diving much more difficult.

BALTOPS 22 was chosen as cover for the undersea operation:

The Norwegians were key to solving other hurdles. The Russian navy was known to possess surveillance technology capable of spotting, and triggering, underwater mines. The American explosive devices needed to be camouflaged in a way that would make them appear to the Russian system as part of the natural background—something that required adapting to the specific salinity of the water. The Norwegians had a fix.

The Norwegians also had a solution to the crucial question of when the operation should take place. Every June, for the past 21 years, the American Sixth Fleet, whose flagship is based in Gaeta, Italy, south of Rome, has sponsored a major NATO exercise in the Baltic Sea involving scores of allied ships throughout the region. The current exercise, held in June, would be known as Baltic Operations 22, or BALTOPS 22. The Norwegians proposed this would be the ideal cover to plant the mines.

The Americans provided one vital element: they convinced the Sixth Fleet planners to add a research and development exercise to the program. The exercise, as made public by the Navy, involved the Sixth Fleet in collaboration with the Navy’s “research and warfare centers.” The at-sea event would be held off the coast of Bornholm Island and involve NATO teams of divers planting mines, with competing teams using the latest underwater technology to find and destroy them.

The explosives were initially to be installed with a 48-hour delay, but Executive vacillation suggested a greater distance between BALTOPS 22 and the detonation was needed to maintain plausible deniability:

The Americans at work in Norway operated under the same dynamic, and dutifully began working on the new problem—how to remotely detonate the C4 explosives on Biden’s order. It was a much more demanding assignment than those in Washington understood. There was no way for the team in Norway to know when the President might push the button. Would it be in a few weeks, in many months or in half a year or longer?

The C4 attached to the pipelines would be triggered by a sonar buoy dropped by a plane on short notice, but the procedure involved the most advanced signal processing technology. Once in place, the delayed timing devices attached to any of the four pipelines could be accidentally triggered by the complex mix of ocean background noises throughout the heavily trafficked Baltic Sea—from near and distant ships, underwater drilling, seismic events, waves and even sea creatures. To avoid this, the sonar buoy, once in place, would emit a sequence of unique low frequency tonal sounds—much like those emitted by a flute or a piano—that would be recognized by the timing device and, after a pre-set hours of delay, trigger the explosives.

The decision is made:

On September 26, 2022, a Norwegian Navy P8 surveillance plane made a seemingly routine flight and dropped a sonar buoy. The signal spread underwater, initially to Nord Stream 2 and then on to Nord Stream 1. A few hours later, the high-powered C4 explosives were triggered and three of the four pipelines were put out of commission.

Discuss.
