Current level of technology required by country frequently needing courage (5,2,3,3)
I believe the answer is:
state of the art
'current level of technology required' is the definition.
I know nothing about this answer so I cannot judge whether it can be defined by this definition.
'country frequently needing courage' is the wordplay.
'country' becomes 'state' ('state' can be a synonym of 'country'**).
'frequently' becomes 'oft' (I've seen this before).
'needing' is a charade indicator (letters next to each other).
'courage' becomes 'heart' (heart is a kind of courage).
'state'+'oft'+'heart'='STATE-OF-THE-ART'
'by' is the link.
Can you help me to learn more?
(Other definitions for state of the art that I've seen before include "Highest level of development at a particular time" , "Highest level of development at the present time" , "Technologically up-to-date" , "Modern" , "Latest developments" .)
