Country originally annexing Crimea out of order (7)
I believe the answer is:
america
'country' is the definition.
(United States of America)
'originally annexing crimea out of order' is the wordplay.
'originally' says to take the initial letters.
'out of order' indicates anagramming the letters.
The first letter of 'annexing' is 'a'.
'crimea' anagrammed gives 'merica'.
'a'+'merica'='AMERICA'
(Other definitions for america that I've seen before include "Camera I used in New World" , "country targeted by 3 [ROMNEY]" , "Name of two continents" , "Race aim (anag)" , "The US" .)
