Maybe killing Sadat causes military action (7,3)

I believe the answer is:

crimean war

I'm a little stuck... Click here to teach me more about this clue!

'military action' is the definition.
(Crimean War is an example)

'maybe killing sadat' is the wordplay.
'maybe killing' becomes 'crime' (I can't explain this - if you can you should give a lot more credence to this answer).
'sadat' becomes 'anwar' (I've seen this before).
'crime'+'anwar'='CRIMEAN WAR'

'causes' acts as a link.

Can you help me to learn more?

(Other definitions for crimean war that I've seen before include "1850s conflict" , "Hostilities" , "Conflict in 1853-56" , "conflict with Russia" .)

I've seen this clue in The Telegraph.
