Rajesh, You forget that child marriage was so common in our country, and even now, it is followed in some places.
I am not here to fight or defend or spread hatred... but to suggest that common man in any country would want peace, friendliness and prosperity. It is politics, military, extremist religion, and media which stops us from being friends. And, you and me know that, we cannot change anything one fine day.
What happened is happened. You cannot change the past. The cultural remains of the past cannot be wiped out in an year or 10.
At least in the modern times, let the nations try to grow themselves, rather than not spending money and time and energy fighting between themselves.
