he is a guy that defeated Israel , without dispute , at least for a week , an absolute cause for the dislike or maybe envy . And ı would say he wasn't killed because he signed a peace deal . It would have been harsher for the "world" to see him back in the Arab League , victory somehow crowned . Just like Russians were thrown out in July 1972 , and they had to replace the Migs and various other stuff for October1973 , because China would have done the same by 1976 ...
Sadat was successful in defense, and took the initiative in peace. I don't think the 'world' had a problem with Sadat who was awarded the Nobel prize, just the Arab League who booted him out, and the extremists who assassinated him.
