Russians are very good as sowing discord and creating panic among the population, but if you look at the facts things are not so bleak.
- If closing down Nordstream would really lead to the collapse of the German economy then the EU would have lifted the sanctions. While they can accept some hardships to beat Russia, they would not kill their economy to do so.
- Just look at the gas futures price in the EU: https://www.theice.com/products/27996665/Dutch-TTF-Gas-Futur... Since the full closure of Nordstream gas prices have actually gone down showing that the gas market has already priced the closure, and as time will pass it will go down even more (since people will see that we have enough gas & Putin's threats are taken less and less seriously mostly because he has run out of things to threaten with)
So dont panic and trust Western leaders a bit more.
