Enemy's confused by sycophants (3,3)
I believe the answer is:
yes men
'sycophants' is the definition.
(I've seen this before)
'enemy's confused' is the wordplay.
'confused' indicates an anagram.
'enemys' is an anagram of 'YES-MEN'.
'by' is the link.
(Other definitions for yes men that I've seen before include "Obedient camp-followers" , "Poodles" , "Affirmative male sycophants" , "lapdogs?" , "Willing conformers" .)
