I'd suggest to use the word boundary markers \< \>

:%s/\<\([A-Z]\)\>/\1./g

This nicely solves a couple of issues in one go.

(Hint: assume you had a title like "... in the US and ...".
Not using boundary markers would turn US into "US.", probably not what
you want...  Even if not strictly required for some given input, it's
generally a good idea to craft regexes as robust as possible against
unexpected input.)
