That would explain El Al’s purchase of 787’s to replace both their 767’s and 747’s. That way El Al would get a modern fleet for their passenger service while freeing the 767 fleet to be sold off to the IDF for conversion into tankers.

I don’t see why they convert 767s into long range bombers capable of dropping large bunker busting bombs. The 767 refueling aircraft could refuel F-15s to provide escort all the way to Iran.
