One reality check...who do you think prints the fake Indian currency whose only aim is to derail Indian economic growth?
And who does North Korea fight with - Japan? China? or Russia? .... same reason. You can really hate some one if you are close enough. Even many Indians could be "hating" pakistan .... and those very people don't know about china.
I know, it's a bit too far (atleast as of now), to say North Korea / South Korea is same as India / Pakistan / Bangladesh.
But saying that we're completely unrelated to Pak / BD .. is also denying reality.
There are just too many cross border relations .... but have you heard a Pakistani marrying an iranian or a chinese?
Just a few years back ... Musharaff (born in Delhi) was head of state of Pakistan .. and MMS (born in Pak) still heads indian govt.
Nobody says, MMS is a "foreign-born" head of state .. unlike Sonia Gandhi.
MMS has Indian citizenship "by birth". By the way, same for my parents .... father born in pindighev (near Rawalpindi city) but his passport says his country of birth is "Undivided India" not Pakistan. (This is standard accepted practice for those born in Pakistan before 1947 and moved to India).
Anyway, not stretching things .... even if India / Pak / BD don't unite into one nation ... we will always be atleast like West Germany and East Germany (which were separate nations) .... and quarelling all the time.
And once all our economies develop .. quarrels will gradually reduce due to great economic interdependence.
