Yes and no.

Since the Russian invasion in February, Europe has been working out how to get by without Russian gas. For this winter, stocks are high enough that Europe can probably get by without gas rationing or a major hit to GDP (although this also depends on what the weather's like). There's also a variety of short-term (increasing gas flows from North Africa) and longer-term (increased renewables energy production, more LNG terminals) efforts to eliminate the need for any Russian gas. That goal is, the last I've seen, ready to be hit in 2024.

So the real question isn't what happens over the next 6 months, which I suspect will be rather anticlimactic for most observers, but what happens in the 12 following months, especially if Russian seems determined to deliver 0 gas to Europe in 2023.

This sounds like politicians promising something, that they'll fail to deliver in a few weeks... as a european, i've heard this many, many times before. As someone from the balkans, i look at first signs of politicials lieing (they're moving their lips).

This!

Taking into account their long-term planning skills there is no reason to assume they know what they're doing.

I assume they're saying it to avoid a panic or increasing prices.
