Wonder who was behind it. Could be America or Russians .
It’s classic Putinism: Make a big mess. Blame opponent(s) for it.
Why would the Russians do this? All they gotta do is turn a few valves and it’s off. The ability to turn it back on was also their bargaining chip.
But now it’s gone. Hmmm, I wonder who didn’t want Russia and Europe to have a bargaining chip.
