The Ukrainians Need to Be Happy With Any Security Guaranteed Agreement

There are a number of groups that I've spoken to that are working directly with Zelensky's office, at least two or three. So they're probably looking at a menu.

The question is, what will be the results of it? Do you think we're getting closer to a credible plan, something that people can unite?"
