For the hell of it since we're talking geopolitics, let's look at the USA's involvement with Iran.
Iran under the Shah was America’s number one arms customer, accounting for $18.1 billion or 25 per cent of the $71 billion in military orders placed by foreign governments under the Foreign Military Sales program between FY 1950 and FY 1977. Recent sales included 141 Northrop F-SE jet fighters, 160 Hughes TOW missiles. During a May 1972 visit to Iran by the then President Nixon, the Shah was given a virtual carte blanche to purchase anything in the US arsenal except nuclear weapons. Subsequent Iranian purchases reflected the Shah’s ambition to recreate ‘the Great Persian Empire of the Past’, as well as the Nixon-Kissinger policy of relying on ‘friendly’ Third World powers to maintain regional stability in strategic areas. Iranian military purchases rose from $519 million in FY 1972 to a record high for any country of $5.8 billion in FY 1977.
Since his 1972 meeting with Nixon, the Shah consistently sought America’s most advanced and sophisticated weapons. Among his recent purchases are seven Boeing E-3A AWACS (Airborne Warning and Control System) radar patrol planes, a system so sophisticated that CIA director Admiral Stansfield Turner originally testified against its sale on the grounds that US security would be gravely threatened if it fell into the wrong hands. Other advanced arms sold to the Iranians include the Grumman F-14 Tomcat swing-wing jet fighter, the McDonnell-Douglas Harpoon anti-ship missile, the Lockheed P-3C Orion ocean surveillance plane, and the Spruance-class heavy destroyer. Besides these potent arms, the United States also endowed Iran with the capacity to conduct warfare far from its borders. Recent deliveries have included, for instance, twelve Lockheed C-130 Hercules troop-transport planes, thirteen Boeing 707-320L tanker aircraft, 142 McDonnell-Douglas F-4E Phantom deep-strike fighter-bombers and three Tang-class submarines (which cannot even operate in the shallow Persian Gulf). These deliveries have provided Iran with a formidable military arsenal, capable of sustaining conflict at very high levels of violence and at sites far distant from Iranian territorV,
That was a review of the post-Iranian Revolution. Anybody seen the movie Argo? That was a pretty cool movie. Argo **** yourself.
EDIT: Actually that article was written prior to the Iranian Revolution. Jimmy Carter poured a lot of arms into the Shah's iran.
