I see no reason to doubt what Begin and Rabin said: https://comrademorlock.medium.com/three-times-that-israel-rejected-its-right-to-exist-8081042a932a

Blockades do not necessarily mean war; if they do, the US was at war with Cuba for decades. And defense pacts are not offense pacts. We agree that Israel has had a bad relationship with its neighbors ever since it began stealing land.

Why do you think Begin and Rabin were wrong?
