There has been only one group that has been interested in cutting ANY and ALL relationships between Germany and Russia: Neocons (primarily in the US).
It is under Biden that pretty much all major positions have come under the Neocons: the presidency, Sec of State, NSA, leaders of both parties in the Senate, and at least the majority leader in the House. Aside: I recently heard the Republican Speaker of the House, Kevin McCarthy, is expected to visit Taiwan - that is exactly what Nancy Pelosi did as a Democrat - and if he does, then the House to has both leaders in that camp.
Under Trump, there were two influential Neocons: John Bolton as the NSA, and Mike Pompeo as the Sec of State. Neither could do much because other cabinet members and Trump too, did not play along. Today Bolton has a dedicated NGO/think tank that is actively and openly working towards replacing Erdogan of Turkey. And, Pompeo seems to be ready to run against Trump in 2024.
And, prior to that under Obama, when Biden and Nuland were extremely active, however, their boss
Obama said:
U.S. President Barack Obama said that Ukraine "is going to be vulnerable to military domination by Russia no matter what" the United States does.
and, thus kept the Neocons in his administration in check.
Be thankful that Hillary did not win in 2016.
Not to be outdone, Richard Kagan, Victoria Nuland's husband, last week wrote an opinion in Foreign Affairs. He is arguing that the Neocon agenda (go to war with Russia and China) should be funded to the hilt. Else "freedom" will not survive.
And, these guys are supported by Globalists (Sunak) and the World Economic Forum (WEF) (Schwab).
And, make no mistake, they have support - in some shape/form - from Australia, Japan, South Korea, and many others.
