The Pakistani armed forces believe India is the only "external military threat" to the country and the situation is volatile because the two countries do not have any conflict resolution mechanism.
The military shared the "perceived threat" with members of the defence committee of the Senate or upper house of parliament when they visited the Joint Staff Headquarters on Thursday.
The committee, led by Senator Mushahid Hussain, was informed India had purchased weapons worth $100 billion over the past few years, 80% of which were "Pakistan-specific", the Dawn newspaper reported on Friday.
"The Senate defence committee was told...that India was the only external military threat to Pakistan," the report said.
India's acquisition of military hardware is continuing and it would buy weapons worth another $100 billion over the next five years, the chairman of the Joint Chiefs of Staff Committee, Gen Rashad Mahmood, and his team told the lawmakers.
India has more than doubled its military spending over the past decade and Delhi's defence budget for this year was $40.07 billion, the military officials claimed.
These developments require a "continuous evaluation of the situation and upgradation of the response mechanism" by Pakistan, they told the Senate panel.
