Maybe you say we've Big Democracy, But I try to give you insight about the situation, Iraq/Syria was invaded by not small country but America, they disturbed the Norms of the Society now it take Long course to finally settledown the Dust.
In the Confusion you get equal chances of you get Injured like me, there will be no hope who survive for the last day, for example 1947 India Partition it took some time to finally sort the new norms of society
Say Thanks to God it wont happened to india...otherwise you cant survive so long, bcoz ur too big as compared to Iraq/Syria
Itr wont happen becuase we are non violent in nature, tamils wont kill malayalis and malayalis wont kill telugus if there is foreign occupation, even though we are culturally more diverse than iraqi shia and sunnis..
Its all down to culture..
