I believe the answer is:

strew

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

'scatter thus' is the definition.
'strew' can be an answer for 'scatter' (I've seen this before). I am unsure of the 'thus' bit.

'ending the war in the west possibly' is the wordplay.
'ending' suggests the final letters.
'in the' is an insertion indicator.
'possibly' indicates an anagram.
The last letter of 'war' is 'r'.
'west' with letters rearranged gives 'stew'.
'r' placed inside 'stew' is 'STREW'.

Can you help me to learn more?

(Other definitions for strew that I've seen before include "Scatter loosely" , "Scatter untidily" , "Scatter, spread around" , "Sprinkle" .)
