In 2017 Iran started a countdown clock for 

August 5, 2040 if I have the numbers right:

In case of a one-state solution, I would consider it to resolve YES, if that state doesn't have special provisions for Jewish people being able to immigrate (in which case I think it would no longer be Zionist). Any two-state solution would be NO.

If the Iran regime moves the countdown clock further into the future, I would consider that to resolve NO (if I have to fix the date because I mis-added, or the 2017 article was wrong, that's fine though).
