Because Pakistan is not a rational actor. It carries a chip on its shoulder which almost forces Pakistan to behave in a defined and now predictable manner.
Each time the US gives these economic bonanza's in both forms - economic support as well as military aid, in any substantial amount, Pakistan uses this to declare war against India and change even the little stability that South Asia has. Its military planners always devise some way in which in their minds Pakistan's strategic disadvantage(in your words) gets neutralized and Pakistan comes out on top.
In 1965, bolstered by treaties of SEATO and CENTO, US aid in massive quantities and US supplied military weapons, Pakistan military started a war to capture Kashmir.
In 1999, once against Pakistan launches a war.
It is not me, but your Military establishment who you must question, over why they continue to do so.
Ergo, from empirical evidence, it is clear that arming or aiding Pakistan will lead to no other outcome than instability in South Asia.
Don't pray. Start a campaign and force your Government and military to stop requesting aid.
