Russia reduced supply before the explosions to perform maintenance on the pipes, but sanctions hindered obtaining the necessary parts. Perhaps, it was in the area inspecting the pipelines.

The US has sanctioned and obstructed Russian oil and gas supplies since the mid-20th century, but European manufacturing relied on inexpensive energy, especially in Germany. Europe and Russia benefitted from the relationship, strengthening ties and economies.

Ukraine sabotaged European transit pipelines, prompting Russia and European partners to construct the Nord Streams, completing NSII just before the invasion.

The US urged Europe to import US LNG in 2018, requesting the EU to agree to a minimum volume of imports, which it declined.

The US vehemently opposed the Nord Streams and fought tirelessly to prohibit NSII from coming online. The unanswered question is why are European energy and Russian supply the US business.

Europeans who relied on Russia bear the brunt of high energy costs and deindustrialization, and the mass protests throughout Europe demonstrate the uneasiness. The EU did not want to disconnect its inexpensive energy source, and Russia intended to maintain its revenue, but who knows?

Russia engaged in a costly war against Ukraine yet sabotaged its money pot. Sure, it's possible but unlikely, and I wonder if the US is investigating the renowned journalist's findings.
