The statement that best analyzes the foreign policy of Clement Attlee compared to that of Winston Churchill is:
Attlee was more willing to trust the Soviet Union than Churchill after WWII.
This statement reflects the general consensus that Attlee's Labour government was more open to dialogue and cooperation with the Soviet Union in the early Cold War period, whereas Churchill was more skeptical and critical of Soviet intentions, famously coining the term "Iron Curtain" to describe the division between the West and the Soviet bloc.
