HELP ME SUMMARIZE
The British Foreign Office has informed us that it is inclined to bring about a coup d'état in Iran, replacing the Mosaddegh government by one that would be more "reliable," if the United States government agreed to cooperate. You will recall the British embassy on October 8 gave us a paper that outlined the possible ways of meeting the threat that would be posed if the communist party of Iran (which is supported by the Soviet Union) took advantage of Mosaddegh's weakness to seize power. Since then, the State Department and CIA have had three meetings with British representatives. The British believe that there is virtually no chance of an oil settlement* with Mosaddegh and they have little hope that his government will be able to prevent a communist takeover. The British do not appear to have a specific candidate in mind as the leader of the suggested coup, but they believe that several of the "old guard" politicians and more moderate nationalist leaders would be good candidates.
The CIA believes that the project is probably feasible and that it could be handled in a way that British and American connection with it could never be proven. However, many things could go wrong. Furthermore, it must be assumed that the Iranians would charge the British with complicity in any sudden political development of this sort, with or without proof, and that this charge would be echoed by the Soviet bloc.
There is also the danger of possible violent Soviet reaction, especially if the coup was not completely successful from the beginning.
*The Mosaddegh government had nationalized the Iranian oil industry, which had been under the control of a company controlled by the British government.
