Ukraine ought to blow the gas line in a way to blame the Russians. That would get Europes attention fast and hurt Russias income big time.
First, that would be in keeping with the rest of the dishonesty we have seen in coverage of this war.
Second, it would cripple Europe's economy overnight while Russia would continue to sell oil to China, India, Turkey and others....in other words, your plan sucks.
Finally, it would spike world oil prices to nearly $300 per barrel, collapsing our economy as well and paving the way for The Great Reset.
