Poland, the Baltic countries, Ukraine, Romania, beg to differ. They know who the real bully on the block is.
Also it’s not in US interests for Iran to have free rein over the Middle East, which Russia in its typical bullying fashion promotes.
What the Secretary Zinke has actually said is that the USA can use its military might to block a competitor's shipments such as shooting at the ships laying the pipelines in the Baltic or Black seas.
Russia doesn't 'broker energy', Russia produces it. The routes we want to use to export it are no business of Poland, the Baltic countries, Romania or whoever else. And our denial to use their territory and/or pipelines is no bullying, sorry.
