That the new pipeline will bypass old ones which run through the Ukraine is likewise to the benefit of Germany, not Russia. The pipeline infrastructure in the Ukraine is old and near to disrepair. The Ukraine has no money to renew it. Politically it is under U.S. influence. It could use its control over the energy flow to the EU for blackmail. (It already tried once.) The new pipeline, laid at the bottom of the Baltic sea, requires no payment for crossing Ukrainian land and is safe from potential malign influence.
