Excerpt (conclusion):

The Biden administration blew up the pipelines but the action had little to do with winning or stopping the war in Ukraine. It resulted from fears in the White House that Germany would waver and turn on the flow of Russia gas—and that Germany and then NATO, for economic reasons, would fall under the sway of Russia and its extensive and inexpensive natural resources. And thus followed the ultimate fear: that America would lose its long-standing primacy in Western Europe.
