Popular view has answer for first of international's attack (8)
I believe the answer is:
invasion
'attack' is the definition.
(I know that invasion is a type of incursion)
'popular view has answer for first of international's' is the wordplay.
I cannot quite see how this works, but
'popular' could be 'in' ('in' can mean trendy) and 'in' is located in the answer.
'answer' could be 'a' (abbreviation eg in Q and A) and 'a' is present in the answer.
'first' could be 'i' (I in Roman numerals eg Elizabeth I) and 'i' is located in the answer.
'of' could be 'o' and 'o' is located in the answer.
This explanation may well be incorrect...
Can you help me to learn more?
(Other definitions for invasion that I've seen before include "Unwelcome intrusion" , "Offensive" , "Entry by force by an army" , "Hostile incursion" , "Unwelcome encroachment on another country" .)
