Jain Dharma is consistent as a spiritual ideal, but the worldly application can be difficult. Jain ethics do not say, “let the innocent perish.” They say: protect life without hatred and without intentional himsā as far as possible.

So for an island of Jains, the Jain response would be:

• Use nonviolent protection first: warning, evacuation, shelter, negotiation, diplomacy, legal protection, community planning.
• Build preparedness: food, water, medical aid, communication, rescue arrangements, and mutual support.
• Seek protection without harming others whenever possible.
• If force is unavoidable, Jain thought still treats it as karma-heavy and spiritually regrettable, so the aim remains to reduce violence, not glorify it.

In Jain view, the question is not, “Who will save us by killing others?” The Jain answer is: save life through ahimsā, wisdom, restraint, and compassionate courage.

So yes, the modern world is imperfect. But Jain Dharma does not abandon its principle because the world is difficult. It teaches that even in danger, one should try to remain as nonviolent as circumstances allow.
