Yes, the dot is necessary for this form.  Alternately, you could phrase
it with relative names:

europe		NS	ns0.europe

Not only "can", but "must", otherwise anyone trying to get to the site
will not be able to find the name server!

Again, it is legitimate to use relative forms:

ns0.europe		A	www.xxx.yyy.zzz

Relative forms versus absolute are a style and maintainability issue
only.  ;-)
