No American intelligence (4)
I believe the answer is:
nous
'intelligence' is the definition.
(I've seen this before)
'no american' is the wordplay.
'american' becomes 'US' (United States).
'no'+'us'='NOUS'
(Other definitions for nous that I've seen before include "Common sense (sl.)" , "Native wit" , "How the French describe their own" , "we recognised in Nancy" , "Knowledge, experience" .)
