The Islamic Republic highlighted a tonal shift in foreign relations with Israel when Iranian President Hassan Rouhani used social media in September to offer greetings on Rosh Hashana, the Jewish New Year. In an unwavering response, Israeli Prime Minister Benjamin Netanyahu used the opportunity to counter with an emphatic, aggressive speech against Iran at the UN General Assembly.

Netanyahu’s reaction makes clear that even in the wake of warming US-Iran relations, Israel is left with growing worry regarding the United States’ commitment to ally Israel’s own national security. More importantly, Israel is actively working to hinder a successful nuclear deal for Iran. At the end of last week, negotiations attempting to limit Iran’s nuclear program were put on hold before a resolution could be reached. France insisted that the proposed limitations for capping Iran’s atomic-bomb-making capabilities weren’t harsh enough. Despite these differences, John Kerry, the US secretary of state, noted that “significant progress” had been made on these issues. In reciprocation, during a defiant speech, Iran’s supreme leader, Ayatollah Ali Khamenei, characterized Israel as “the warmongering rabid dog … that does not even deserve to be called an animal.”

Still, many are left wondering how the relationship between Israel and Iran might change in the context of tentative congeniality between the United States and Iran. Historical disputes involving Israel demonstrate that we should not accept Netanyahu’s static assumption that the Islamic Republic of Iran by nature can never have a normal relationship with Israel.

Just as Israel was once an intrinsic part of the relationship between Egypt and the United States, today it is paralleled as an intrinsic part of the relationship between Iran and the US Bilateral ties between the United States and Egypt (and now Iran) create a metaphorical one-sided triangle, the other sides of which link the United States to Israel and link Israel to Egypt (and now Iran).
