The correct answer is: "The Axis Powers would have to give up completely without any compromises".
The Allied countries demanded an unconditional surrender from the Axis powers, because they intended to intervene those totalitarian countries and to judge its leaders.
This actually happened when the US army from the West, and the Soviet Red army from the East managed to conquer the whole German territory, and when the US forced Japan to surrender after the nuclear attack. WWII finally came to and end and these two powers, Germany and Japan were intervened by the allied powers, demilitarized and their respective leaders were judged.
