See
how Roosevelt is sitting in the middle power-seat legs spread out and toes
pointed outward, bearing in mind his psychical issues that may have required
that this photo be taken with all three men sitting rather than standing while others
stood around them. He still looks powerful. Notice how Stalin is smiling but
his hands are in a protective castle wall over his vulnerable lower belly/pelvis
Showing he needs to protect his manliness and his outside foot out toes pointed outward show he is ready to go. And Churchill
too is smiling and in good spirits. These men are dividing up Europe and they are happy to have the chance to show their power and do it their way.
