What makes you think the Pantsir is a high priority target for the IAF?
Syria has now 37 Pantsir systems. It has attacked dozens upon dozens of air defense sites, and yet only twice had it decided it was important enough to destroy Pantsir systems. Explain this logic.
What's the basis of your claim that the IAF got a Pantsir every time they've gone after them?
The basis for my claim is that if it's seen as a high priority enough goal for the IAF, they can devote sufficient resources to defeat any number of air defense systems in Syria as they please.
Theoretically, the Pantsir can be overwhelmed fairly easily if it's just a standalone system, enabling its saturation from a standoff system via dirt cheap JDAM bombs.
