Why would keeping the pipelines operational not be a strictly dominant (over blowing the pipelines up) strategy if reducing EU support and aid to Ukraine is the objective? Having the pipeline there but not delivering anything through it results in the same lack of gas, but also adds the option of dangling the possibility of delivering some in return for support and aid being reduced. The most obvious beneficiary of the pipelines being blown are those countries that would stand to lose from the option of resumed delivery being available (and potentially taken) by Germany, that is, Ukraine, Baltic countries (who have a cultural and geopolitical interest in its victory) and the US (which has a geopolitical interest in its victory and a financial interest in selling LNG to Germany). Why do you think that these potential benefits to the countries in question are not real?
