The following are probably the top two things analysts most frequently  forget:

#1. Iranian Twelver messianism: “In this context, mutual assured destruction, the deterrent that worked so well during the Cold War, would have no meaning. At the end of time, there will be general destruction anyway. What will matter will be the final destination of the dead — hell for the infidels, and heaven for the believers. For people with this mindset, MAD is not a constraint; it is an inducement.”
August 22 – By Bernard Lewis The Wall Street Journal Aug. 8, 2006 l

#2. “Democratic state for all of its citizens”: This means only one thing:
revoking the Law of Return which allows all Jews to immigrate to Israel and become citizens. Here’s how this is spelled out in “The Democratic Constitution” proposed by Adalah – The Legal Center for Arab Minority Rights in Israel:

Citizenship
15. The laws of citizenship and immigration will be established on the basis  of the principle of anti-discrimination and will define the arrangements by  which the State of Israel will grant citizenship to:
A. Anyone who was born within the territory of the State of Israel and whose  parent was also born within the territory of the State of Israel;
B. Anyone who was born to a parent who is a citizen of the state;
C. The spouse of a citizen of the state;
D. Those who arrive or remain in the state due to humanitarian reasons,  including those who are persecuted on the basis of political background.
