btw, IMO Putin has already threatened Europe with shutting off Nord Stream gas...but actually turning the valve to "OFF" makes it clear that HE is the 'Bad Guy' causing a humanitarian crisis...however, if "Someone" sabotages the pipeline, he gets what he wants...i.e. no gas to Europe...while introducing "doubt" as to who's responsible.
Germany, et al, are not yet where they need to be for Russian gas replacements...why on earth would they or the U.S. sabotage the lines NOW?...get real...it was Putin.
