American's vote against looking over conclusion to cyber-attack (4)
I believe the answer is:
yank
'american's' is the definition.
(Yank can informally mean an American)
I don't understand the remainder of the clue.
Can you help me to learn more?
(Other definitions for yank that I've seen before include "Wrench" , "American from the North" , "Statesman?" , "Pull roughly" , "one seen crossing the Atlantic?" .)
