Of chief importance to Iraq was [[Khuzestan Province|Khuzestan]] which not only boasted a substantial Arab population, but rich oil fields as well. On the unilateral behalf of the [[United Arab Emirates]], the islands of [[Abu Musa]] and the [[Greater and Lesser Tunbs]] became objectives as well. With these ambitions in mind, Hussein planned a full-scale assault on Iran, boasting that his forces could reach the capital within three days. On September 22, 1980, the Iraqi army invaded Iran at Khuzestan, precipitating the [[Iran–Iraq War]]. The attack took revolutionary Iran completely by surprise.
