In Churchill`s view, the agreement was very favourable to Great Britain, as the EAM largely controlled Greece, which Stalin accepted as an area of British influence, while Britain in turn recognized Bulgaria and Romania, which already occupied the Red Army, as in the Soviet zone of influence.  From a British perspective, Greece, in the British sphere of influence, put an end to any possibility that the EAM could take power and then give the Soviet Union bases in Greece, whose situation made that nation the key to control of the eastern Mediterranean, which was far more important to Churchill than the rest of the Balkans.  The fact that Roosevelt did not share Churchill`s enthusiasm for the restoration of King George II as King of Greece was a decisive factor in securing his own agreement with Stalin on Greece and excluding the Americans.  Churchill feared that if Roosevelt was involved in discussions about the future of Greece, the Americans might side with the Soviets and agree to recognize the EAM as a legitimate government of Greece.  During the dekemvriana fighting in Athens, Roosevelt made a statement rejecting the British eAM fighters, and privately stated that he was appalled by the way the British openly recruited the collaborative security battalions that had loyally served Nazi Germany to fight with them the EAM.  Similarly, American media coverage of the Dekemvriana was largely hostile to the British, with American journalists criticizing Churchill for recruiting security battalions to fight for the unpopular King George.  When he realized that dismantling Europe in areas of influence could not be beautiful if the word came out, Churchill suggested to Stalin that it might be a good idea to burn half the sheet of paper with the percentages on it. (Staline said it was normal for Churchill to keep him.) The two foreign ministers, Anthony Eden and Vyacheslav Molotov, negotiated the percentages on 10 and 11 October. The result of these discussions was that the percentages of Soviet influence in Bulgaria and, more importantly, Hungary were changed to 80 percent – other than that, no other country was mentioned.
In response to American assertions that Britain is making a “policy of power” in Greece, Churchill responded in a speech: “What is power politics?… Is a navy twice as big as any other navy in world power politics? Is the world`s largest air force, with bases in all parts of world power politics? Do we have all the gold in the politics of world power? If that is the case, we are certainly not guilty of these offences, I must unfortunately say.
