This is prime time for China and Russia to do anything they want. Dementia Joe aint gonna do S!!@##
Yes Einstein, dementia Joe is not going to risk an all out conventional war with the red army, and he's not looking forward to an nuclear war either.
He's waiting until the harsh sanctions will cripple the russian economy and it will collapse. Just as the soviet union collapsed when they could not afford the arms race and support all their "allies".
Russia is a vast country, 140 million inhabitants, but their economy is only about the same size as the Italian economy (60 million people).
Russian people will become a lot poorer, no better future for them, their children or grandchildren, and putin is 69, he will not live forever.
In the mean time the US economy is growing fast, while the russian economy is being ruined.
Biden has made the right choices.
