Conflict with Germany sent up in sketch (4)
I believe the answer is:
draw
'sketch' is the definition.
(I've seen this in other clues)
'conflict with germany sent up' is the wordplay.
'conflict' becomes 'war' (war is a kind of conflict).
'with' says to put letters next to each other.
'germany' becomes 'd' (international vehicle registration code).
'sent up' says the letters should be written backwards.
'war'+'d'='ward'
'ward' back-to-front is 'DRAW'.
'in' is the link.
(Other definitions for draw that I've seen before include "Extract" , "Make picture" , "Snag" , "Make representation" , "Depict - raffle" .)
