A lot of US politicians are involved in the Ukrainian energy and gas industry since Euromaidan (see Burisma for example). Their support for increasing gas transit tariffs caused huge increases in energy prices in Europe recently, and is why Russia has built Nord Stream 2.
The US wants to keep Europe isolated from Russia and have some control via Ukraine. They make millions off the tariffs whilst we struggle to afford electricity.
As a fellow EU citizen, I wish we could have a peaceful disarmament. Have the US withdraw its military bases from Europe, stop funding and arming extremist militias in Ukraine, stop interfering in Nord Stream 2, etc. and abolish NATO. Whilst Russia could also stop funding separatists and allow Ukraine to join the EU, and the EU could permit Nord Stream 2 and form a self-defence force.
