From October 1972 until the abrupt end of the Kurdish intervention after March 1975, the CIA "provided the Kurds with nearly $20 million in assistance," including 1,250 tons of non-attributable weaponry.[101] The main goal of U.S. policy-makers was to increase the Kurds's ability to negotiate a reasonable autonomy agreement with the government of Iraq.[102] To justify the operation, U.S. officials cited Iraq's support for international terrorism and its repeated threats against neighboring states, including Iran (where Iraq supported Baluchi and Arab separatists against the Shah) and Kuwait (Iraq launched an unprovoked attack on a Kuwaiti border post and claimed the Kuwaiti islands of Warbah and Bubiyan in May 1973), with Haig remarking: "There can be no doubt that it is in the interest of ourselves, our allies, and other friendly governments in the area to see the Ba'thi regime in Iraq kept off balance and if possible overthrown."[103][104] After Nixon's resignation in August 1974, President Gerald Ford was briefed about the Kurdish intervention on a "need-to-know" basis—leaving Kissinger, former CIA director and ambassador to Iran Richard Helms, Arthur Callahan (chief of the CIA Station in Tehran), and Callahan's deputy—to actually implement the U.S. policy.[105] To prevent leaks, the State Department was not informed of the operation.[106] In fact, the State Department had dispatched Arthur Lowrie to establish a U.S. Interests Section in Baghdad shortly prior to Nixon's decision to support the Kurds; the Interests Section officially opened on October 1, 1972.[107] Lowrie repeatedly warned that there was a power struggle between moderates and extremists within the Iraqi Ba'ath Party, and that the Shah's aggressive posture towards Iraq, combined with the Ba'ath Party's belief that the U.S. sought to overthrow it, empowered the extremists while forcing Iraq to turn towards the Soviet Union for arms resupply.[108] Helms and the CIA rejected Lowrie's analysis and his proposal that the U.S. try to improve relations with Iraq, with Helms stating "[We] are frankly skeptical that in practice we could help the moderates without building up our extremist enemies." The CIA went further, producing a report that cautioned "the level of political violence is very high ... This is not a happy situation nor a happy government for the US to try to do business with."[109][110] After a failed coup attempt on June 30, 1973, Saddam consolidated control over Iraq and made a number of positive gestures towards the U.S. and the West, such as refusing to participate in the Saudi-led oil embargo following the Yom Kippur War, but these actions were largely ignored in Washington.[111]
