State starts to undermine those admirable heroes (4)

I believe the answer is:

utah

'state' is the definition.
(Utah is an example)

'starts to undermine those admirable heroes' is the wordplay.
'starts to' suggests taking the first letters.
The first letters of 'undermine those admirable heroes' is 'UTAH'.

(Other definitions for utah that I've seen before include "The American Morman state" , "American location" , "Bryce Canyon US state" , "US state, capital Salt Lake City" , "Great Salt Lake state" .)

I've seen this clue in The Telegraph.
