The capabilities of the Egyptian air defense in dealing with low footprint targets and stealth targets

[The SC]

F-35s were always far more vulnerable then the common PDF laymen knew.. Not only Egypt but majority of the region can neutralize them

Maybe not the majority .. very few countries in the region can counter them. So you can't take any chances with them..They might be vulnerable somehow but still are the most advanced fighters out there.. One need to counter them through all means that take advantage of their vulnerabilities.. Just like Egypt did and continues doing..
