How so?
Hell, there's a Wikipedia page listing all of the Russia-Ukraine gas disputes (https://en.wikipedia.org/wiki/Russia%E2%80%93Ukraine_gas_dis...). One of the stated motivations for Nord Stream 2 was to improve reliability of gas to Europe in case Russia decided to cut off the gas because of a spat with one of the transit countries.
Russia switched off the gas 7 years after Putin was screaming from the rooftops that the US sticking ABMs in Eastern Europe was a red line for Russia. That's Russia being an unreliable partner?
