1) It proves that the US Deep State is made up of Free Traitors not Free Traders
2) The only blackmail there's ever been associated with Europe buying Russian gas was back when the USSR was still around and Ukraine forced a shutdown of the flow, not Russia. The only current blackmail is the EU insisting that gas still flow through Ukraine even though there's bound to be five or ten percent stolen every single day, day in, day out, as long as the gas flows. IOW, blackmail to make the Russian costs higher than they would otherwise be and even with that LNG is far more expensive.
IMHo, Trump will go along with anything that pisses the Europeans off because their being pissed makes it more likely he can collapse NATO. The Deep State and the Brussels crowd are desperate to keep NATO going because it's a huge cash cow where the deficiencies are easily hidden and the immense amount of paperwork for every little thing makes tracking theft down very difficult.
Yup. A lot of people made a lot of money off of the Ukraine “transit fees”. Illegal money that is.
Sanctioning a Swiss pipeline company for building a pipeline that Russia, Germany & other European nations want is what John McCain wanted.
It weakens US influence in the world.
