Yes, President Joe Biden declared at a televised press conference that there would be no more Nord Stream 2 if Russia invaded Ukraine

The Nord Stream pipelines were sabotaged, which came as a big surprise, and it is no surprise that responsibility for the sabotaging of the Nord Stream pipelines is disputed, but since the sabotaging might be treated as an act of war and increased the risk of a nuclear war, no one claimed credit for it.

The United States says that Vladimir Putin is responsible for the sabotage.

Russia's war with Ukraine has not gone as Putin hoped, but does Putin know that Hitler ordered the flooding of Berlin's subway to delay the fall of his bunker and decide that sabotaging those pipelines was a smart move to let the world know he refuses to be humiliated over Ukraine?

It's hard to believe.

Putin had to have been peeved when the Russian flagship in the Black Sea was sunk by Ukraine (perhaps with United States assistance) and his luxurious yacht was seized in the West, but there are other ways for him to take out his frustrations.

Did the Biden administration figure that Russia's invasion of Ukraine was going badly for Putin and sabotaging the pipelines would lead to Putin's fall from power before he could use Russia's nuclear weapons.

President Biden is 78 and apparently has not taken a cognition test, but that's hard to believe too.

Yes, President Joe Biden declared at a televised press conference that there would be no more Nord Stream 2 if Russia invaded Ukraine: “I promise you that we will do it.”

Did President Biden suddenly remember that promise and direct or arrange for that sabotage?

Who else could have done it?

Did China want a war between the United States and Russia and sabotage the pipelines in the hope of provoking World War III?

I doubt it.

Dagmar Henn opined:

The list of possible suspects is comparatively short...in alphabetical order, Germany, Denmark, Finland, France, Great Britain, Italy, Norway, Austria, Russia, Sweden, Switzerland, South Africa and the United States.

Henn further opined: "it is unlikely that in the West it will ever become public who is responsible for this," because "the Baltic Sea is one of the best monitored bodies of water on this planet."

The sabotaging was not a simple task because, as Henn explained, "the individual pipe sections of Nord Stream 2 weigh 50 tons; the metal tube is lined with concrete and then with bitumen and is buried under the seabed. I saw them being transported at Mukran, every single piece on a heavy truck that was only allowed inside the factory premises because the payload exceeded normal limits. The pipes lie at a depth of 40 meters. There are also technical divers who work at such depths, but their equipment is far too conspicuous. So basically only combat divers remain."

The operating company of Nord Stream 1 stated that “the destruction that occurred within one day on three tubes of the Nord Stream pipeline system is something unprecedented…and it is now impossible to determine the timeframe for the repair work on the gas pipeline structure.”

Henn rejected the idea that Russia is the culprit in emphatic terms: "Even the biggest NATO friend would have to admit that sabotaging the pipelines only relieves political pressure on EU governments, especially Germany’s; this cannot be in the Russian interest."

Henn also excluded South Africa for geographical reasons, leaving either members of NATO or aspirants to be members.

Henn suggests this possible explanation of the sabotage:

It may be that the United States found it necessary to put additional pressure on Chancellor Olaf Scholz in his full pants quarantine. It may also be that Scholz himself agreed to such an act because there is some panic in front of the angry population.

It's hard to believe that either the United States or Germany would have conspired to sabotage the pipelines, but it's apparent that the pipelines were sabotaged.

After the fiasco known as the United States withdrawal from Afghanistan, would the Biden Administration have ordered the Pentagon to do the sabotaging and kept such a thing from leaking?

That seems unbelievable.
