Ultimate success, stealth deployed by the French: I don't like it (3,4,5)

I believe the answer is:

the last laugh

'ultimate success' is the definition.

'stealth deployed by the french i don't like it' is the wordplay.
'deployed' is an anagram indicator.
'by' says to put letters next to each other.
'the french' becomes 'la' ('the' in French).
'i don't like it' becomes 'ugh!'.
'stealth' is an anagram of 'thelast'.
'thelast'+'la'+'ugh'='THE LAST LAUGH'

I've seen this clue in The Everyman puzzle in The Observer.
