This is a strange thing to say. Pakistan only has so many resource for military. It is clearly better to spend that money on the Air Force than air defense. When you have control of your own air space, the most that your adversary can do is lob missiles and drones over. That does limited damage. Nytimes report pretty much showed that both military overstated their impact on the opposing military bases. Pakistan bases had a few more crates & damaged buildings, but nothing that prevent flight operations.
In fact given that Pakistan has limited resources, it was probably conserving missiles against most incoming attacks.
