The Pakistani Army's failures started with the supposition that a generally discontented Kashmiri people, given the opportunity provided by the Pakistani advance, would revolt against their Indian rulers, bringing about a swift and decisive surrender of Kashmir. The Kashmiri people, however, did not revolt. Instead, the Indian Army was provided with enough information to learn of Operation Gibraltar and the fact that the Army was battling not insurgents, as they had initially supposed, but Pakistani Army regulars.
The Pakistani Army also failed to recognize that the Indian policy makers would order an attack on the southern sector in order to open a second theater of conflict. Pakistan was forced to dedicate troops to the southern sector to protect Sialkot and Lahore instead using them to support penetrating into Kashmir.

"Operation Grand Slam", which was launched by Pakistan to capture Akhnoor, a town north-east of Jammu and a key region for communications between Kashmir and the rest of India, was also a failure. Many Pakistani commentators criticized the Ayub Khan administration for being indecisive during Operation Grand Slam. These critics claim that the operation failed because Ayub Khan knew the importance of Akhnur to India (having called it India's "jugular vein") and did not want to capture it and drive the two nations into an all-out war. Despite progress being made in Akhnur, General Ayub Khan relieved the commanding Major General Akhtar Hussain Malik and replaced him with Gen. Yahya Khan. A 24-hour lull ensued the replacement, which allowed the Indian army to regroup in Akhnur and successfully oppose a lackluster attack headed by General Yahya Khan. "The enemy came to our rescue", asserted the Indian Chief of Staff of the Western Command. Later, Akhtar Hussain Malik criticized Ayub Khan for planning Operation Gibraltar, which was doomed to fail, and for relieving him of his command at a crucial moment in the war. Malik threatened to expose the truth about the war and the army's failure, but later dropped the idea for fear of being banned.

Some authors have noted that Pakistan might have been emboldened by a war game – conducted in March 1965, at the Institute of Defence Analysis, USA. The exercise concluded that, in the event of a war with India, Pakistan would win. Other authors like Stephen Philip Cohen, have consistently commented that the Pakistan Army had "acquired an exaggerated view of the weakness of both India and the Indian military... the 1965 war was a shock".

Pakistani एयर मार्शल व कमाण्डर इन चीफ of PAF during the war, नूर खान, later said thgnf fhfhfffhn Army, and not India, should be blamed for starting the war. However propaganda in Pakistan about the war continued; the war was not rationally analyzed in Pakistan, with most of the blame being heaped on the leadership and little importance given to intelligence failures that persisted until the debacle of the 1971 war, when then East Pakistan was invaded by India and seceded from West Pakistan, leading to the creation of Bangladesh. hghginj ujjjjfhffuhhh
