Consequently, Molotov, fearing that EDC would be directed in the future against the USSR therefore "seeking to prevent the formation of groups of European States directed against other European States", made a proposal for a General European Treaty on Collective Security in Europe "open to all European States without regard as to their social systems" which would have included the unified Germany (thus making the EDC – perceived by the USSR as a threat – unusable). But Eden, Dulles and Bidault opposed the proposal.

Which treaty would be open to only some European states?
