This is the first time since I've been on this forum that I saw a Pakistani member take the bull by its horn.
PAF doesn't have a high end fighter. Without a high end fighter, you can't fight the IAF. This is such a "right under your nose" situation that most people simply fail to see it.
In General Hostage's words:
If I do not keep that F-22 fleet viable, the F-35 fleet frankly will be irrelevant. The F-35 is not built as an air superiority platform. It needs the F-22.

Today, all the way in 2018, it doesn't matter how many JF-17s and F-16s are present in an air force, they are all irrelevant without high end aircraft. You will notice that even the Israelis are asking for more F-15s, even though they are taking delivery of F-35s, an aircraft that is touted to be far superior to the F-15.

They are even willing to bring to life 40-year-old decommissioned American F-15Ds.
