Yousuf Al-Kuwailit, who writes the editorials of the Saudi government daily Al-Rai, opined in a December 7, 2014 editorial that, despite the tension that has ostensibly prevailed between the U.S. and Iran ever since the Islamic Revolution, in practice there is secret cooperation between them. As part of this cooperation, he said, Iraq has become nothing but an arena for assuring the interests of these two countries, and Iran has been granted freedom of action in Syria and Lebanon.
Referring to the U.S.-Iran nuclear talks, he said they were a farce that would end in contracts and deals, and perhaps even an alliance, between the two countries. He therefore called on the Arabs not to regard the U.S. as a reliable ally, and warned that the U.S. may force the Gulf states to reconcile with Iran, to the detriment of their interests.
The following are excerpts from the article: 
"The U.S. appointed the Shah as policeman of the Arab Gulf, turned Iran into a base for conflict with the USSR, and provided Iran with up-to-date weaponry and a nuclear reactor. [Iran, for its part] attempted to take advantage of this situation, as it saw itself as a superpower. [Only] the strength of the USSR... prevented Iran from undertaking military adventures outside its own borders. With [the rise to power of Ayatollah Ruhollah] Khomeini, despite everything that happened at the U.S. Embassy [in Tehran in 1980], when dozens of its staffers were taken hostage and [then-U.S. president Jimmy] Carter carried out a reckless and unsuccessful operation [in attempt to free them]... [despite all this] nothing spoiled the U.S.'s relationship with this country, which it considers one of its strategic and economic outposts by virtue of its location and its history. So the farce... about Iran's nuclear reactors and non-conventional weapons has taken a clear and final direction, in the form of several deals [between the two countries]...
"Cyrus [the Great], who attacked and destroyed the Arabs, is the spiritual father of the Nazi trend that has characterized Iran's governments, whether secular or religious. Racial supremacism vis-├á-vis the Arabs is a popular [Iranian] obsession. It exists and it is eternal, and even if the mullahs don black turbans [indicating that they are] descendants of the Prophet and have Arab roots, they do not really recognize these roots, but do this only in order to market their national policy to us, prior to marketing their religious school of thought [i.e. the Shi'a]. Anyone who thinks that diplomatic arrangements are aimed at anchoring coexistence between the Arabs and the Iranian 'Aryans' is disregarding the nature of the historical reasons [for the tension between the two sides] and its deep roots in the [Iranian] public mentality.
"In order to better understand the unfolding of events, [we need to realize that] the U.S. and its allies set out the initial plan to divide the Arab [regions] a long time ago, and that the Sikes-Picot agreement is only the first outcome [of that plan]. [We must also realize] that handing over Iraq [to Iran], and annexing Syria and later Lebanon to it, and the [silent] agreement [between the two countries] that Iran would have a free hand in these countries - all these are only a prelude to more dangerous activity.
"[Accordingly], relying on the U.S. or thinking it a reliable ally without properly understanding the strategic changes and aims, place us in a situation [of self-delusion], because all the historic elements of power see how positions and policies change but interests remain. This principle will be ultimately applied to all the countries that have a relationship with the U.S., whether economic or strategic, because the Arabs are part of a geographic area whose borders are changing, including through the disappearance of the centrally[-ruled] state in favor of states [based on] sect or nationality.
"One simple event in recent days is the Iranian Air Force's incursion into Iraq to attack ISIS positions, which the U.S. confirmed but Iran denied. At the same time, the U.S. also ignores the incursion of [Iranian] ground troops under the command of [IRGC Qods Forces commander] Qassem Soleymani into Iraq, [which has been taking place] ever since the U.S. first started managing [Iraq's] affairs... [In fact,] U.S. Secretary of State John Kerry stated that any Iranian military attack on ISIS was positive. This exposes the significant coordination between the two countries, and belies the statements of U.S. military circles denying any cooperation or coordination [with Iran] in the war on ISIS...
"In the era of [former Iraqi prime minister Nouri] Al-Maliki, Iraq become nothing but an arena for assuring the interests of two players: Iran and the U.S. This came about as part of an agreement that began with [head of the occupational authority of Iraq after the 2003 invasion Paul] Bremer, and no Iraqi government will put an end to it, unless the Iraqis [dare to] oppose their homeland's dependence on another country - something that is difficult and complicated to do.
"Ultimately, even if the talk about the American-Iranian hostility is true, everything points towards new contracts between the two which are likely to turn into alliance. We could possibly see catastrophic days if the U.S. forces the Gulf states to reconcile with Iran, which will end in a way that will not serve our interests. This is an outcome that should not surprise us, if the reality of [U.S.-Gulf] friendship evolves into [U.S.] dictates [to the Gulf states]."
