None of them are going to be eating many peanut butter sandwiches.
They put big bucks in those accounts mostly to lead the russian government and the americans to believe that that is where their big bucks are.
Meanwhile, you may recall - my memory is a little fuzzy here- that there was the leak of clients who worked with that Panama law firm or financial firm or something. Almost all of Putin's immediate buddies had accounts there. These guys most definitely do not put all their eggs in one basket. They have dozens of accounts like that around the world.
I am in favor of heavy duty sanctions but they are mostly like kicking the dog. Sanctions go on. Putin keeps any territory he keeps. Sanctions get lifted down the road. Putin still keeps the territory. Putin rolling in the cash when he drive the price of oil and gas up.
Where Putin will have near term trouble is with the Iranians. Putin is a snake and the Iranians are snakes and they work together, except when it is not in their interest they will knife each other. You might say that they are ...errr...well.....snakes.
The Iranians have died and gone to heaven because Biden and Putin sanctions have made the US suddenly even more dependent on foreign oil RIGHT WHILE ANOTHER NUKE DEAL IS BEING NEGOTIATED. Let's just say that the Iranians are going to get a Saaaaaaaaaaaaweet deal and their sanctions will be lifted soon.......and they sitting on a pile of oil THAT IS ALREADY IN STORAGE. They are about to become a YUGE beneficiary of this flap with their buddy Vlad. But, hey, nothing personal, just bidness.
It's further down the road, but Biden will wake up some morning with a boner for talking with Venezuela too.
