Vitalik Buterin is born in russia and a friend of Putin.
Do you have any evidence? What exactly makes you so sure he is a friend of Putin?

You can google Buterin and Putin and see that they have met a few times.
With the sactions inplace it's only possible to apply sanctions after ethereum 2.0 is inplace.
What does this statement actually mean?

Ethereum 2.0 will be protected by 1% of the supply. 1% of the money in the network will decide which transactions are valid or not. If angry miners go together and form a malicious staking pool with 1.5% of the network, they can block all the transactions or force the network to mutate. If a government agency does something similar, it's easy to create a killswitch of the network.
Ethereum blockchain 1.0 is the safest bank in the world, and ethereum 2.0 is the opposite. Especially iun the few first months after the merge.
