Israel's longstanding strategic goal has always been the erasure of Palestine and the expulsion of its people. For its part, since the 1979 revolution, Iran has pursued a strategy that seeks to export its ideology and expand its influence across the region with the goal of positioning itself as the dominant political, economic and military power.
From the onset of its mission, the Iranian regime has used the Palestine issue to rally support for its 'revolutionary' ideology by intentionally conflating the two struggles. Upon his return from exile to Tehran in 1979, Ayatollah Khomeini famously said, “Today Iran, tomorrow Palestine."
Faded euphoria
It sounded ideal and even inspired Yasser Arafat to travel to Iran to meet its new 'revolutionary' leader. But the euphoria of revolution quickly faded as Arabs soon realised Khomeini's true goal was to dominate their region. Even more sinister was the realisation that although Iran and Israel don't have relations publicly, they cooperate privately when their interests align through tacit understandings.
There are ample examples in history that back this assertion. One is that during Israel's 1982 siege of Beirut, Khomeini refused to support the Palestine Liberation Organisation (PLO), choosing instead to back the Lebanese Shiite Amal Movement, which would attack Palestinian refugee camps in Lebanon.
