Inept force destroyed Utopian state (10)

I believe the answer is:

perfection

I'm a little stuck... Click here to teach me more about this clue!

'utopian state' is the definition.
'perfection' can be an answer for 'state' (perfection is a kind of state). I'm not certain of the 'utopian' bit.

'inept force destroyed' is the wordplay.
'destroyed' indicates an anagram.
'inept'+'force'='ineptforce'
'ineptforce' is an anagram of 'PERFECTION'.

Can you help me to learn more?

(Other definitions for perfection that I've seen before include "Faultlessness" , "Highest state" .)

I've seen this clue in The Times.
