Win over Germany is a rare miracle for starters (6)
I believe the answer is:
disarm
'win over' is the definition.
(thesaurus)
'germany is a rare miracle for starters' is the wordplay.
'germany' becomes 'd' (international vehicle registration code).
'for starters' indicates taking the first letters.
The initial letters of 'rare miracle' is 'rm'.
'd'+'is'+'a'+'rm'='DISARM'
(Other definitions for disarm that I've seen before include "Placate" , "Charm, win over" , "Abandon weapons" , "Confiscate weapon or mollify" , "Deprive of weapons or win over" .)
