Looks like Russians are not very well prepared. Lack of communication. They don't know where they are going, or what the current situation is.
In fact, there are already several proofs that this is exactly the case. Captured Russian soldiers say that they were not warned that they would be sent to war in Ukraine.
Putin secretly planned the invasion and lied to the entire world until the very last moment, so it is not surprising that the soldiers received orders at the last minute.
Well, actually, it's happening. US is considering to freeze reserves of Central Bank of Russia - over $643 billion:
That is good. I would confiscate everything from them. All the dollars in the banks, all the gold bars, all the properties outside Russia's borders. Everything they own. I bet that would have an impact.
No doubts that it will increase oil and gas price in Europe. But I think it's simply not acceptable to feed country which literally started war. Sanctions against Russia will hurt Europe too, but every decision have it's price and priorities should be chosen.
I am from Europe, and I say let it be. Winter is almost over, and Europe will survive without their gas.
