This very concise video explains the back story and roles of the UK and US governments in controlling that of Iran’s to ensure the West and their oil companies had control of Iranian oil. The engineered coup by MI6 and the newly formed CIA (the original document of the plan can be found online) shows the lengths that Britain and the US meddled in world affairs as well as the hypocrisy of all the freedom and democracy rhetoric.
The decision to replace a Prime Minister Mossaddegh, a man of true democratic values with an oppressive monarch was to ultimately backfire. The subsequent suffering and discontent of the Iranian people was to sow the seeds of the Iranian revolution decades later, cause an oil crisis, disrupt the stability of the entire region, catalyse 2 wars as well as keeping the relationships between Iran and the western world borderline hostile. And people wonder why the rest of the world hates the west.
