The difference now is that Russia is receiving Ruble as the payment. That is all Russia has asked for. It doesn't matter how natural gas flows around once it has been paid for. Actually it makes pure economic sense. Think about it. After EU and US posted sanction on Russia, what does Russia need...
Yes, including Poland that supported US-led occupation of Iraq. For victims, it is a very simple matter. Only those who look for excuses prefer to treat it as something complicated.
Of course. That means they want to have their payback time but they have no capability to make it happen. So they talk, as loudly as they can. Why not? as you said.
They are the ones who jump up and down the most and call for no-fly zone over Ukraine while they barely have an air force. It is their payback time to get back to Russians, only by the hands of other NATO members.
Maybe it is payback time.

You don't get it. The purpose pursued by US is to weaken Russia, not to help Ukraine win the war.
The same way US supported Mujahedin to fight Soviets. The same way China supported North Vietnam to fight Americans.
