Globe, maybe, within which one may operate (7)
I believe the answer is:
theatre
I believe this is a double definition.
'globe maybe' is the first definition.
(Shakespeare's Globe is an example)
'within which one may operate' is the second definition.
(I've seen this before)
(Other definitions for theatre that I've seen before include "A tether (anag.)" , "Play venue" , "Play scene" , "war zone" , "Place for operation or play" .)
