Russian gas stops flowing to Europe via Ukraine

I'm still wondering why they didn't just shut everything down on day 1.

If my "friend" Greg had a deal with Bill and wanted to run a garden hose across my yard, and bill starts shooting at my house one day and smashing down my fence and shed, Greg will either be okay with my cutting the garden hose or Greg is not a friend.

And if Greg keeps buying stuff from Bill, Greg is a piece of shit partially responsible for the bullets hitting my house and smashed fence.
