It certainly wasn't Germany or Russia... North Stream allows Russia to excuse the military presence on Baltic Sea (to protect the pipe but also cut of aid to Nato allies over the sea). Therefore finding anything that shows threat to the pipe is in favor of Russia. Of course this might have multiple levels. It was planted by US/UK, Russia strengthens military presence close to Sweden, Sweden moves closer to the Nato alliance. I am no expert in this area but I think that your understanding is a bit too simplistic.
