Fighting words in Chirac’s resignation statement? (4,2,6)
I believe the answer is:
cest la guerre
I believe this is a double definition.
'fighting words' is the first definition.
('c'est la guerre' is 'it's war' in French)
'chirac's resignation statement?' is the second definition.
(the resigned observation 'that's war' in French)
'in' is the link.
(Other definitions for cest la guerre that I've seen before include "It was said to explain shortage" , "That's war! (French)" .)
