Ian Bremmer discusses the World In (more than) 60 Seconds:

Number one, what's the story with the new COVID strain in Britain?

Well, I mean, it's a mutation. Apparently, it is equally combatable by the vaccines that we've developed, and I've heard that directly by some of the people that are running those companies. So, it's not a concern about the ability that we have to stop the disease once we get vaccinations, thank God. But it is a problem in terms of how much more quickly the virus can be transmitted. Now, in the United Kingdom, they do an awful lot of testing, especially compared to many countries in Europe, and they have found an extensive amount of this new strain, which has led them to bring the UK into Tier 4, as they call it, which means basically Christmas is canceled. No one's going anywhere. Everything's locked down. That also has meant that a lot of countries have suspended travel to the United Kingdom, which I understand, but we've already seen some of this new strain in Italy, for example. I suspect it's going to pop up in a bunch of other countries in the continent. If it's everywhere, do you really want the additional pain economically?
