I agree partially...your blood doesn't decide your identity...it's actually your environment that makes you who you are...whatever Sunita Williams has accomplished has been because of her being an american. But i disagree with the point that Kalpana Chawla's achievments should'nt make a true indian proud...chawla was essentially 'Made in India'. She has been raised in Karnal in a completely indian environment. Hence Chawla's success is yet another medal of honour for India.
