Securing National Interest is the supreme goal of foreign policy. War is also considered as a means to secure national interest.
However, just war theory sets out principles for a war to be ethical, the war must be:
- Waged by a legitimate authority (State)
- In a just cause.
- Waged with right intentions.
- Have a strong probability of success.
- Be a last resort.
- Be proportional.
In addition, there are three principles for conduct in war:
- Discrimination (distinguishing between enemy combatants and non-combatants).
- Proportionality (harm must be proportional to gains achieved).
- Actions must be militarily necessary.
Apart from these, there are Indian principles of dharmayuddha, universal peace and nonviolence, Panchsheel, nonaggression, no first use.
Even in the current war, PM Modi has tried to open a new window of peace in Ukraine by conveying his message to Russian President Putin that “Era of war has ended.”
