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

'battle of 1990' is the definition.
I don't know anything about this answer so I cannot judge whether it can be defined by this definition.

'rug flaw affected' is the wordplay.
'affected' is an anagram indicator.
'rug'+'flaw'='rugflaw'
'rugflaw' is an anagram of 'GULF WAR'.

Can you help me to learn more?

(Other definitions for gulf war that I've seen before include "First armed conflict between USA and Saddam Hussein" , "Hostilities in 1991" .)

I've seen this clue in the Sydney Morning Herald.
