Will fastest guns win this international competition? (4,4)
I believe the answer is:
arms race
'competition?' is the definition.
(arms race is a kind of competition)
'will fastest guns win this international' is the wordplay.
I cannot quite see how this works, but
'guns' could be 'arms' (I've seen this in another clue) and 'arms' is found within the answer.
The remaining letters 'race' is a valid word which might be clued in a way I don't see.
This may be the basis of the clue (or it may be nonsense).
Can you help me to learn more?
(Other definitions for arms race that I've seen before include "military competition" , "Potentially dangerous competition" , "International competition for weapons" , "A hostile international competition" , "rush to war" .)
