Possibly cater for counter-attack (5)

I believe the answer is:

react

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

'counter-attack' is the definition.
I can't judge whether this definition defines the answer.

'possibly cater' is the wordplay.
'possibly' indicates an anagram.
'cater' anagrammed gives 'REACT'.

'for' acts as a link.

Can you help me to learn more?

(Other definitions for react that I've seen before include "Take" , "Retaliate" , "provide an answer" , "Behave in response" , "Acknowledge" .)

I've seen this clue in The Globe and Mail.
