On the pretext of restoring order, the Russians occupied Northern Iran in 1911, and maintained a military presence in the region for years to come. During World War I, the British occupied much of Western Iran, and fully withdrew in 1921. The Persian Campaign commenced furthermore during World War I in Northwestern Iran after an Ottoman invasion, as part of the Middle Eastern Theatre of World War I. As a result of Ottoman hostilities across the border, a large amount of the Assyrians of Iran were massacred by the Ottoman armies, notably in and around Urmia. Apart from the rule of Aqa Mohammad Khan, the Qajar rule is characterized as a century of misrule.

paragraph_text: In the Western world, Persia (or one of its cognates) was historically the common name for Iran. On the Nowruz of 1935, Reza Shah Pahlavi asked foreign delegates to use the term Iran, the endonym of the country, in formal correspondence. Since then, in the Western World, the use of the word ``Iran ''has become more common. This also changed the usage of the terms for Iranian nationality, and the common adjective for citizens of Iran changed from`` Persian'' to ``Iranian ''. In 1959, the government of Mohammad Reza Shah Pahlavi, Reza Shah Pahlavi's son, announced that both`` Persia'' and ``Iran ''could officially be used interchangeably. However the issue is still debated today.

paragraph_text: From the successful naval reactor program, plans were quickly developed for the use of reactors to generate steam to drive turbines turning generators. In April 1957, the SM - 1 Nuclear Reactor in Fort Belvoir, Virginia was the first atomic power generator to go online and produce electrical energy to the U.S. power grid. On May 26, 1958 the first commercial nuclear power plant in the United States, Shippingport Atomic Power Station, was opened by President Dwight D. Eisenhower as part of his Atoms for Peace program. As nuclear power continued to grow throughout the 1960s, the Atomic Energy Commission anticipated that more than 1,000 reactors would be operating in the United States by 2000. As the industry continued to expand, the Atomic Energy Commission's development and regulatory functions were separated in 1974; the Department of Energy absorbed research and development, while the regulatory branch was spun off and turned into an independent commission known as the U.S. Nuclear Regulatory Commission (USNRC or simply NRC).

Despite its commitment to NPT, there are reports indicating that Muammar Gaddafi of Libya either made unsuccessful attempts to build or entered in an agreement to purchase a nuclear weapon from nuclear - armed nations. In the 1970s -- 80s, Gaddafi made numerous attempts to accelerate and push forward his ambitions for an active nuclear weapons program, using the nuclear black market sources. However, after the end of the Cold War in 1991, Gaddafi sought to resolve its nuclear crises with the United States aiming to uplift the sanctions against Libya, finally agreeing to authorize rolling back Libya's weapons of mass destruction program on December 2003.

paragraph_text: By the 1500s, Ismail I from Ardabil, established the Safavid Dynasty, with Tabriz as the capital. Beginning with Azerbaijan, he subsequently extended his authority over all of the Iranian territories, and established an intermittent Iranian hegemony over the vast relative regions, reasserting the Iranian identity within large parts of the Greater Iran. Iran was predominantly Sunni, but Ismail instigated a forced conversion to the Shia branch of Islam, by which the Shia Islam spread throughout the Safavid territories in the Caucasus, Iran, Anatolia, and Mesopotamia. As a result, thereof, the modern-day Iran is the only official Shia nation of the world, with it holding an absolute majority in Iran and the Republic of Azerbaijan, having there the 1st and 2nd highest number of Shia inhabitants by population percentage in the world.

paragraph_text: Economic sanctions against Iran, such as the embargo against Iranian crude oil, have affected the economy. Sanctions have led to a steep fall in the value of the rial, and as of April 2013 one US dollar is worth 36,000 rial, compared with 16,000 in early 2012. Following a successful implementation of the 2015 nuclear and sanctions relief deal, the resulting benefits might not be distributed evenly across the Iranian economy as political elites such as the Islamic Revolutionary Guard Corps have garnered more resources and economic interests.

paragraph_text: The Countering America's Adversaries Through Sanctions Act, CAATSA (H.R. 3364, Pub.L. 115–44), is a United States federal law that imposed sanctions on Iran, North Korea, and Russia.

paragraph_text: Since 2005, Iran's nuclear program has become the subject of contention with the international community following earlier quotes of Iranian leadership favoring the use of an atomic bomb against Iran's enemies and in particular Israel. Many countries have expressed concern that Iran's nuclear program could divert civilian nuclear technology into a weapons program. This has led the UN Security Council to impose sanctions against Iran which had further isolated Iran politically and economically from the rest of the global community. In 2009, the US Director of National Intelligence said that Iran, if choosing to, would not be able to develop a nuclear weapon until 2013.

paragraph_text: Many sports in Iran are both traditional and modern. Tehran, for example, was the first city in West Asia to host the Asian Games in 1974, and continues to host and participate in major international sporting events to this day. Freestyle wrestling has been traditionally regarded as Iran's national sport, however today, football is the most popular sport in Iran. Because of economic sanctions, the annual government's budget for sport was about $80 million in 2010 or about $1 per person.

paragraph_text: The USSR's invasion of Afghanistan was only one sign of insecurity in the region, also marked by increased American weapons sales, technology, and outright military presence. Saudi Arabia and Iran became increasingly dependent on American security assurances to manage both external and internal threats, including increased military competition between them over increased oil revenues. Both states were competing for preeminence in the Persian Gulf and using increased revenues to fund expanded militaries. By 1979, Saudi arms purchases from the US exceeded five times Israel's. Another motive for the large scale purchase of arms from the US by Saudi Arabia was the failure of the Shah during January 1979 to maintain control of Iran, a non-Arabic but largely Shiite Muslim nation, which fell to a theocratic Islamist government under the Ayatollah Ruhollah Khomeini in the wake of the 1979 Iranian Revolution. Saudi Arabia, on the other hand, is an Arab, largely Sunni Muslim nation headed by a near absolutist monarchy. In the wake of the Iranian revolution the Saudis were forced to deal with the prospect of internal destabilization via the radicalism of Islamism, a reality which would quickly be revealed in the seizure of the Grand Mosque in Mecca by Wahhabi extremists during November 1979 and a Shiite revolt in the oil rich Al-Hasa region of Saudi Arabia in December of the same year. In November 2010, Wikileaks leaked confidential diplomatic cables pertaining to the United States and its allies which revealed that the late Saudi King Abdullah urged the United States to attack Iran in order to destroy its potential nuclear weapons program, describing Iran as "a snake whose head should be cut off without any procrastination."

paragraph_text: In the resulting Battle of Pusan Perimeter (August–September 1950), the U.S. Army withstood KPA attacks meant to capture the city at the Naktong Bulge, P'ohang-dong, and Taegu. The United States Air Force (USAF) interrupted KPA logistics with 40 daily ground support sorties that destroyed 32 bridges, halting most daytime road and rail traffic. KPA forces were forced to hide in tunnels by day and move only at night. To deny matériel to the KPA, the USAF destroyed logistics depots, petroleum refineries, and harbors, while the U.S. Navy air forces attacked transport hubs. Consequently, the over-extended KPA could not be supplied throughout the south. On 27 August, 67th Fighter Squadron aircraft mistakenly attacked facilities in Chinese territory and the Soviet Union called the UN Security Council's attention to China's complaint about the incident. The US proposed that a commission of India and Sweden determine what the US should pay in compensation but the Soviets vetoed the US proposal.

Question: Why did the developer of Transformator in 1958 complain about the action of the US to the organization that imposed sanctions against Iran because of Iran's nuclear program?
