Absolutely, those steps need to be taken. How effective they will be is questionable, but it's certainly demonstrable that being booted out of the G7 meant something. It cuts off access, and I think that needs to be happening on all spheres; it must be clear that if you behave like this, you're not a member of the international community. There are discussions around the EU of excluding them from a lot of those committees, so that needs to continue. I think that sends a strong message, mainly to people around Putin, because I don't think Putin actually really cares; it's about the people around him who don't want to be international pariahs, although that's what he's making them into.
