1. True.
Foreign Policy is drawn up to foster the national interest of defence and economic development.
National interest is considered to be the goal and foreign policy is considered to be the means to achieve it.
Goals of nations change with changes in conditions and time.
Accordingly, national interest also changes. These changes are reflected in foreign policy.
Therefore, foreign policy is always dynamic.
2. True.
Nuclear weapons are extremely destructive.
Hence, it is necessary to, make consistent efforts so that they are never used. Two treaties have been made to stop the spread of nuclear weapons.
1. Nuclear Non-Proliferation Treaty (NNPT)
2. Comprehensive Test Ban Treaty (CTBT).
The conditions of both these treaties are of benefit to big nuclear powers and they put unfair restrictions on developing countries, hence India has not signed either of these treaties.
