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.
Two of the pipelines, which were known collectively as Nord Stream 1, had been providing Germany and much of Western Europe with cheap Russian natural gas for more than a decade. A second pair of pipelines, called Nord Stream 2, had been built but was not yet operational.
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.
