Calm Down. These were claims, they were never verified that Israeli F16's were in India to target Pakistan. A few F16's won't have made any difference when the Indians fielded MIG29's and Mirage 2000's.
Pakistan has not once, but multiple times assured the Israelis that Pakistan's nukes are only aimed at India. If the Israelis considered Pakistan a big threat, why would they supply PAF with spares for the F16's during the 90's when Pakistan was sanctioned by the US?
The first drone that Pakistan built, its processing computer and avionics had ELBIT Systems written on it. Feel free to Google what ELBIT systems is. Not even going to go in detail for the equipment that was bought from Israel to aid our indigenous Radar, ELINT and Avionics program.
