In late September 2018 — four years before the Russian invasion of Ukraine — the American President gave a speech, a prescient and foretelling speech, at the United Nations in which he cautioned the German nation not to become dependent upon Russia for its energy needs.
In that speech the American President said:
Reliance on a single foreign supplier can leave a nation vulnerable to extortion and intimidation. That is why we congratulate European states, such as Poland, for leading the construction of a Baltic pipeline so that nations are not dependent on Russia to meet their energy needs. Germany will become totally dependent on Russian energy if it does not immediately change course.
He was referring to the completion of NordStream II and the continuing operation of NordStream I.
