Iraq–Israel relations refer to the bilateral ties between the State of Israel and the Republic of Iraq. Due to Iraq's non-recognition of Israel as a legitimate state since the latter's establishment in 1948, the two countries have not had any formal diplomatic relations. The Hashemite Kingdom of Iraq was a part of the Arab coalition that declared war on and invaded Israel shortly after its establishment, sparking the First–Arab Israeli War, and the two states have since then been in a continuous state of hostilities. Iraqi forces also participated in the Third Arab–Israeli War and the Fourth Arab–Israeli War in 1967 and 1973, respectively. In 1981, Israel carried out Operation Opera in Ba'athist Iraq, in which the Israeli Air Force bombed and successfully destroyed an Iraqi nuclear reactor that was under construction at the Tuwaitha Nuclear Research Centre near Baghdad; the reactor had been attacked and partially damaged by Iran during its Operation Scorch Sword, which had been carried out a year prior to the Israeli strike amidst the Iran–Iraq War. During the 1990–1991 Gulf War, Iraq carried out a missile campaign against Israel, in which it launched 42 modified Scud missiles (designated Al-Hussein) at Israeli cities with the strategic objective of provoking Israel into launching retaliatory attacks and potentially jeopardizing the multinational coalition formed by the United States against Iraq, which had full backing and extensive contributions from other Muslim-majority states; Israel did not respond to the Iraqi missile attacks due to American pressure, and Iraq failed to gather support for its occupation of Kuwait. The post-2003 Republic of Iraq continues to be a strong supporter of the Arab League boycott of Israel. All Iraqi passports are invalid for travel to Israel and Israeli passports are likewise invalid for entry into Iraq. Alongside a number of other Arab and Muslim-majority countries, Iraq is designated as a hostile state under Israeli law, and Israeli citizens may not visit the country without a special permit issued by the Israeli Interior Ministry. History Until the 2003 Iraq War The British in the 1930s built the Mosul–Haifa oil pipeline from Western Iraq through the British-ruled Emirate of Transjordan then to Haifa, in Mandatory Palestine. During the Anglo-Iraqi War, the Irgun - an Israeli independence movement - participated in the British invasion of Iraq.
