India believes that the plan for restructuring the Security Council should be broad-based. This means that it should involve a wide range of countries and take into account the perspectives and interests of different regions of the world. A broad-based approach is seen as essential for ensuring the legitimacy and effectiveness of the Security Council in addressing global security challenges.

There are several reasons why India advocates for a broad-based restructuring plan:

1. **Representation**: India emphasizes the need for a more equitable representation in the Security Council. Currently, the Council is dominated by five permanent members (P5) - the United States, Russia, China, France, and the United Kingdom - who have veto powers. India argues that this structure does not reflect the current geopolitical realities and that more countries should have a say in decision-making on global security issues.

2. **Democratic principles**: India believes in the principles of democracy and equality. It argues that a broad-based Security Council would be more democratic and inclusive, allowing a greater number of countries to participate in decision-making processes. This, in turn, would enhance the legitimacy and credibility of the Council's actions.

3. **Regional representation**: India emphasizes the importance of regional representation in the Security Council. It argues that decisions taken by the Council often have a direct impact on specific regions, and therefore, countries from those regions should have a seat at the table. This would ensure that the perspectives and interests of different regions are adequately taken into account.

4. **Enhanced effectiveness**: India believes that a broad-based Security Council would be more effective in addressing global security challenges. With a greater diversity of perspectives and expertise, the Council would be better equipped to understand and respond to complex issues. It would also be more likely to garner support and cooperation from a wider range of countries, increasing the effectiveness of its decisions.

In conclusion, India advocates for a broad-based plan for restructuring the Security Council because it believes in equitable representation, democratic principles, regional representation, and enhanced effectiveness. By involving a greater number of countries and taking into account a wide range of perspectives and interests, India believes that the Security Council can better fulfill its mandate of maintaining international peace and security.
