Over any such tangled wave of problems the S-1 secret would be dominant and yet we will not know until after that time probably, until after that meeting, whether this is a weapon in our hands or not.

The Japanese campaign involves therefore two great uncertainties; first, whether Russia will come in though we think that will be all right; and second, when and how S-1 will resolve itself.

We think it will be shortly afterwards, but it seems a terrible thing to gamble with such big stakes in diplomacy without having your master card in your hand.

Henry L. Stimson Quotes
