Ideal padre, a militarist in part (5)
I believe the answer is:
dream
'ideal' is the definition.
(I've seen this before)
'padre a militarist in part' is the wordplay.
'in part' indicates the answer is hidden within the clue.
'DREAM' is hidden in the letters of 'padre a militarist'.
(Other definitions for dream that I've seen before include "Somniate" , "Trance" , "Aspire" , "Bedroom vision?" , "Sleeping thoughts" .)
