Personally i don't give a hoots ass where Buddha was born, it is recognized by the international community that he was born in Lumbini, which currently is part of Nepal and that my friend is the official recognisition. India  falsely claim that Buddha was born in india or they may also claim jesus was born in south india or for that matter they may claim mt everest is located to the north of india (geographically speaking that is a true statement if you take their capital city to be the waypoint) so what does that matter? they are playing with your weakness and agitating you and you react exactly how they want you to react... there are so many more pressing issues that Nepal needs to address than to ponder and waste our time on this ridiculous argument. 

I will now proceed to opening a bag of pop corn and enjoy people making useless argument about non issue.
