Sir: Pakistan is our motherland and no one has the right to exploit it. We are all free citizens and as Pakistanis we all have some responsibility towards it. It is our duty to defend this country. Pakistan has everything, including natural resources. However, most people do not seem to be happy living here, which is sad indeed.Most politicians are selfish and only think about themselves, not for Pakistan.We can make Pakistan a better place for the younger generation and their children, and they too can do the same for their children.
