देशभङ्गे प्रवासे वा व्याधिषु व्यसनेष्वपि ।
रक्षेदेव स्वदेहादि पश्चाद्धर्मं समाचरेत् ॥

पञ्चतंत्र - मित्रभेद - युद्ध

होमार्थैर्विधिवत्प्रदानविधिना सद्विप्रवृंदार्चनैः
    यज्ञैर्भूरिसुदक्षिणैः सुविहितैः संप्राप्यते यत्फलम् |
सत्तीर्थाश्रमवास होमनियमैश्चान्द्रायणाद्यैः कृतैः
    पुंभिस्तत्फलमाहवे एनिहतैः संप्राप्यते तत्क्षणात् ||

- पञ्चतंत्र, मित्रभेद

Soldiers who die in a war get the same credit of good karma as any of the below - religious rituals being performed by very learned brahmins, rituals that have been performed by generously giving money, visiting many holy places (temples and ashrams), performing various ritualistic penances. All these are comparable to a person being ready to lay down his life to protect other people of his state.

- Panchatantra, Mitrabheda

मनुस्मृति - न युद्धेन कदाचन

साम्ना दानेन भेदेन समस्तैरथवा पृथक् |
विजेतुं प्रयतेतारीन् न युद्धेन कदाचन ||

- मनुस्मृति

First one must exercise reasonable patience. Then We must try to concede some ground - compromise. Then we must try to penetrate the adversary's thinking and try to change it. All these are the methods are to be employed separately or together to win over an enemy. Waging a war is never a solution.

- Manu Smriti
