How Soviets react to military Alliance of Poland-Czech ?
Will Soviet see them more threat than Germany?
This is the real problem I see with this Alliance. First off, the Soviets and the Polish were at odds. Without Poland giving up a large swath of her Eastern territory, they cannot be reconciled and the Soviets won't be willing to support or help them.
Czechoslovakians, on the other hand, were quite cozy with the Soviets. Their cooperation with the Polish would probably be quite heavily influenced by this.
