because the Nazi Germany was captured but in 1965 the invasion was denied and repelled with extreme prejudice and an aggressive defensive stance that caused great fear into the hearts of the force of invasion.
also keep in mind that in that time too, the invasion army outnumbered the defending army by about 1/3. But still as i heard it was a deadly battle of Tanks in which 100 Pak Tanks were able to tame and mutilate 300 Indian Tanks.
The Pakistani side won 65 keep it in your mind.
That was a Great Battle indeed.
Local people volunteered by their esteemed and actualized will to put their lives online for the defense of the country.
Every living soul that resided in Pakistan was enraged and evolved a thirst of blood of the enemy. Mujahids willingly rolled under enemy tanks with bombs to destroy those who dared to try and attack on Pakistan.
