“And the Russians would also be bankrupt as their economy would be devastated without the sale of oil and gas to Europe. They don’t have the infrastructure in the short term to sell the same volume to China or Japan.”
Your post was irrelevant to this factual statement.
Your “factual statement” is fictional.
The FACT is that Europe NOW needs the Russian oil and gas, which amounts to 50% of its energy, and won’t commit an economical hara-kiri, just to please the US.
If America can replace à pied levé Russia’s exports in Europe, go for it!
