We need to add this to the list of predictions that others have made:
In the early 2000s, Hamas leader Bassam Jirrar - based on Koranic analysis, said Israel would end by 2022. A Lebanese cleric agreed with those calculations in 2015.
An Egyptian astrologer predicted in 2007 that Israel would be gone by 2024.
Hamas founder Sheikh Yassin said that it would be 2026 or 2027.
In 2016 Iranian Basij Brigadier General Mohammad Reza Naqdi said that Israel would no longer exist by 2025.
In 2009, Iranian TV and some other conspiracy theory sources claimed (falsely) that there was a CIA report predicting that Israel would not last 20 more years, or 2029.
Essam al-Erian, the deputy head of the Muslim Brotherhood’s Freedom and Justice Party in Egypt, said in 2013 that Israel would disappear within ten years, or 2023.
In 2012, the Ayatollah Khamenei predicted that Israel would disappear, but he didn't name a date. He fixed that in 2015, saying that Israel wouldn't survive another 25 years, or 2040 - well after his death.
Of course, Arabs have been predicting the end of Israel for a lot longer than this.
