Why at times War is the Best Option with Pakistan?

विनय ना मानत जलध जड़ गए तीन दिन बीति। बोले राम सकोप तब भय बिनु होय ना प्रीति

What does it mean

The line 'bhay bin hoye na preet' means that for love or bonhomie to exist, an element of deterrence is necessary, so that the other party thinks twice before offending or crossing you. A weak person, someone no one fears, may not get a lot of respect or equal treatment in his relationships.

Shree Ram prayed samudra at rameshwaram for 3 days to give way to his Army but he didn't budge but as soon as Shree Ram took out his bow and arrow to pierce the ocean he appeared and begged for forgiveness and the construction of Ram Setu started.
