Many of the movies show someone from 'dushman country' doing courageous act and helps the army of other country and that is so Cooooool and greaaaaaaat thing to do.
yes i noticed this theme in almost all indian war movies or indo vs. pak theme films but i haven't watched the last couple of ones because i stopped. it was getting annoying. sometimes they take this patriotism thing too far.
this theme you describe is getting repetitive and so lame. it's like stop it already we get the point. no need to go totally over.
