Pakistan and India are two immediate neighbors having common history and culture; in this way, they should have the warmest ties, but their relationships have remained hostile all the time. Kashmir is very important between the two states, over which three main wars have been fought between them. Despite some important and effective peace initiatives, the main problems in maintaining the bitter taste in bilateral relations remain unresolved. Pakistan has always been pleased to suggest mitigating measures, but Indias response is generally not so good. Today, more than 70 years after independence, both Pakistan and India are not concerned for solving long lasting issues like the Kashmir issue, and water issue. Peace process and stability in South Asia lies between the two major countries. So, South Asian regional security structure is affected by the two main players of this region because they cannot find a peaceful solution of lingering issues.
