The Islamic Republic of Iran has never attacked or invaded its neighbors. The only war in which Iran has been involved since the Islamic Revolution, the Iraq-Iran war in the 1980s, was initiated by Saddam Hussein’s regime. When Iranian forces were attacked with chemical weapons by Saddam’s troops during that war, Iran did not retaliate against the Iraqis due to religious and political considerations.
In contrast, Israel is currently occupying territories of three Arab states, Palestine, Lebanon and Syria, and has launched bloody wars against its neighbors, including against Lebanon in 2006 and Gaza in 2008-2009. In these wars, Israel illegally employed weapons, such as white phosphorus, against civilians and committed numerous war crimes and crimes against humanity, some of which have been reported by UN commissions of inquiry. Others countries of the region, such as Iran or Egypt, have also been threatened by Israeli officials and politicians.
