Neither Nepal nor India existed when Buddha was born. He was a citizen of a state that was neither although i do agree with the official word that he was born in Lumbini, which is a part of nepal. How significant is that? i don't really see any when you compare it to his teaching.

I therefore do not see any relevence for people to blow up this issue because there is a huge anti-indian sentiment and political agenda on both sides that is completely over shadowing Buddha's glory.
