Ill-advised, as far as global alliance is concerned? (6)
I believe the answer is:
unwise
'ill-advised' is the definition.
('unwise' can be a synonym of 'ill-advised')
'alliance is concerned?' is the wordplay.
'alliance' becomes 'un' (UN is an example).
'is concerned?' becomes 'wise' (I can't justify this - if you can you should believe this answer much more).
'un'+'wise'='UNWISE'
'as far as global' is the link.
This may not be right. Some or all of it may belong to another bit of the clue.
Can you help me to learn more?
(Other definitions for unwise that I've seen before include "Foolhardy" , "Not sensible, foolish" , "Ill-judged" , "Not sensible or prudent" , "Rash" .)
