Dr. H. B. Braun's independent geophysical analysis concludes the Nordstream pipeline explosions were caused by mini-nuclear devices, not conventional explosives.

Presenting his findings to the UN Security Council on September 26, 2023, Braun identified distinct seismic signatures consistent with kiloton-range blasts. This rules out a conventional origin, pointing instead to a deliberate act of unprecedented industrial sabotage. The pipelines, capable of transporting 650TWh of natural gas annually (equivalent to 40 nuclear reactors), were destroyed, severing Europe's energy link to Russia and triggering widespread price hikes.

Braun's report, submitted under strict Swiss neutrality without external funding, has been shared with numerous entities including the UN Security Council, NATO, and various governments, yet received no official responses. His work underscores the catastrophic geopolitical and energy security implications of the attack, highlighting a critical gap in international accountability mechanisms.
