Well, the historic response to that question—and not just in Canada but in every other country in the world—says, “Let's just not do anything about it.” That has been the historic response: let's just not do anything. As a result of that, Putin has enjoyed absolute impunity, and it has actually emboldened him to invade neighbouring countries.
Because Putin is a kleptocrat—it's now widely acknowledged that he's a kleptocrat—and he doesn't keep his money in Russia, the one thing we can do is sanction him. In other words, we can sanction his money and freeze his assets so his money is no longer safe. I don't think Putin will start a nuclear war over his money being frozen, because he can't really acknowledge that he has any money. This is their Achilles heel. This is the main way we can get to them in the west. There's no reciprocal way in which they can go about doing anything about this.
