Trade in War

I for example do not understand how it can be possible that Ukraine transports Russian gas on its pipeline network. Not sure if that's still the case though.

Nor do I understand how Europe still buys gas from Russia.. in effect funding and prolonging the war. They seem to be playing both sides. Saying how horrible the Russian regime is, while directly giving it more money. And then giving weapons to Ukraine..

It seems completely morally bankrupt... If instead of Russia it was ISIS, would they still send money just so they have cheap gas? Like at what point would they stop? Do the Russians need to be impaling babies and goosestepping through Red Square?

I also don't understand why Ukrainians don't feel a deep sense of betrayal about this

The issue is complex. Now there is a US president who wants to control all energy supplies to Europe while still talking about new oil deals with Russia:

And wants to control Russian gas to the EU:

Nord Stream has been sabotaged, a huge US LNG deal was forced on the EU in the tariff negotiations. The US leased a corridor from Azerbaijan through Armenia to Turkey that could be a new energy choke point for fossil fuels from Azerbaijan or Turkmenistan (lots of natural gas) to the EU.

The EU is in a pretty bad position right now where it can be blackmailed with energy cutoffs not by Russia but by the US.

The Ukrainians can't feel betrayal because they have kept their own transit pipeline open until 2025, long after Nord Stream was blown up (allegedly by Ukrainians on a sail boat, see the recent arrests).
