hazem: let's take it back to tom burgis. going back to the oligarchs.f you look at the optics of this, is there a messaging problem that the west has with ukrainians? what is going after a few russian billionaires going to do for the millions of ukrainians who are suffering right now? they've got enough money to whether this. -- they've got enough money to weather this. do you think there is a messaging issue in terms of showing ukraine that the west is fully behind them? tom: yeah. actually, i think it goes much further than that. you read the statements that the u.k. and other western governments have made to accompany their sanctions decisions, to justify why whoever is going on this list. there is very little information as far as i can see that we did not know a week ago, a month ago, a year ago, that we did not know that quinn putin murdered -- back when putin murdered someone on the streets of london, or when he next crimea. up until now, our decision has been, we would rather keep the money. there is a mismatch in what we are doing now and what
