I have two copies, copyrights 1966 and 1973.
Both have Israel, ...and Iran...
sounds like you have a printing error, pages accidently left out of that copy.
It might have been just your book. It might have been 100 books. It could have been the entire printing run of that specific edition. That would be a "publisher error".
I would strongly doubt there's any kind of conspiracy with or about Israel, you just got a printing goof.
449 to 480 missing? that takes out the last page of German Machineguns, and removes everything about Greece, Hungary, India, Indonesia, Iran, Israel, and Italy (handguns and most of the rifle section)
So, maybe someone at the bookbinder had an axe to grind against one or more of those countries, but I think its more likely they just screwed up.
