... opposes leaders in the hostile West after rebuking Trump so ... (7)
I believe the answer is:
thwarts
'opposes' is the definition.
The answer and definition can be both to do with social activities as well as being verbs in their -s form.
Perhaps they are linked in a way I don't understand?
'leaders in the hostile west after rebuking trump so' is the wordplay.
'leaders in' says to take the initial letters.
The first letters of 'the hostile west after rebuking trump so' is 'THWARTS'.
Can you help me to learn more?
(Other definitions for thwarts that I've seen before include "Blocks, prevents" , "Frustrates" .)
