I think from the beginning of this engagement, certainly President Putin has discussed this in terms of the security not only of Ukraine but also of Europe. Over the course of these past weeks we have seen Russia's neighbour countries ask for and receive enhanced presence from NATO countries.
There is a lot of anxiety over what President Putin could do. I think we need to stay in touch, be ready to respond and be ready to support with our allies. The rest would be speculation at this point.
