The WWII ended in Europe by decisive defeat of German forces in the West Front, Poland and liberation of France on May, 8, 1945. Consequently, sending supplies to USSR through Iran was no more necessary and that was the main pretext for occupation of Iran. The Iranian government sent out a notice to the embassies of UK, US, and USSR to evacuate their forces as it was mentioned in Tehran Declaration.
The British responded quickly and positively and announced that they were willing to withdraw troops sooner than the six month period after the war. They also started a propaganda against USSR who was hesitating to comply with the terms adding that Bolsheviks were not engaged in the Japan war. This reason would give the British necessary excuses to keep some forces in south both for securing the supply route to far east and protect their interests in the oil fields.
The Toodeh Party was opposed to withdrawal of the Red Army. Their alibi was that Iran was not stable enough and the situation during Reza Shah's reign would be recreated if they left the country. It was clear by then that the Bolsheviks wanted to either install their puppet subordinates if not imposing an unwanted agreement on Iran. A powerful Iran would have meant claims on Azerbaijan, Herat and even Georgia.
The US also replied to the notice positively; stating that they planned to complete their withdrawal as early as June,1. The young Mohammad Reza Shah was flirting with the US at the time and already had employed American advisors. Americans requested keeping 3000 logistic personnel in south alongside 1500 people at the Abadan airport due to war in Japan to which Shah's answer was positive.
None of the occupation forces were willing to pull out troops from Iran indeed. Although UK and US had a comparatively positive instance towards Iran's request, there was no such sign from the Soviets, creating an atmosphere of mistrust. Obviously, they were all trying to gain some more time and enjoy the merits of having a rich country under occupation.
The Big Three agreed to discuss the issue at the Potsdam Conference, July, 16 - August, 2 1945 near Berlin.
