Trump is fighting Nord Stream 2. He raised a wave of indignation in Central and Eastern European countries, which, allegedly, are very concerned about the fate of the Ukrainian transit. Europe, which is facing political collapse due to Brexit, is unable to resist the pressure of the American business-cowboy. Moreover, Eastern European countries will do anything to support their overseas master just for a few cents.
A number of EU states are concerned about the Nord Stream 2 pipeline project and its implications to their energy security. Back in March 2016, leaders of 8 Central and Eastern European states sent a letter to the president of the European Commission objecting to the Nord Stream 2 project as posing risk for the energy security in the region. Such position was also shared by the European Parliament.
