Through Treaty, Soviet Union and Nazi Germany

His successor, Pierre Laval, was sceptical of the desirability and value of an alliance with the Soviet Union. However, after the declaration of German rearmament in March 1935, the French government forced the reluctant foreign minister to complete the arrangements with Moscow that Barthou had begun.

Ratification

The pact was concluded in Paris on 2 May 1935 and ratified by the French government in February 1936. Ratifications were exchanged in Moscow on 27 March 1936, and the pact went into effect the same day. It was registered in League of Nations Treaty Series on 18 April 1936.

Laval had taken the precaution of ensuring that the bilateral treaty agreement was strictly compatible with the multilateral provisions of the League of Nations Covenant and the Locarno Treaties. That in practice meant that military assistance could be rendered by one signatory to the other only after both an allegation of unprovoked aggression had been submitted to the League of Nations, and the approval of the other signatories of the Locarno Pact (the United Kingdom, Italy and Belgium) being attained.

The Franco-Soviet Pact was no longer what Barthou had originally planned, but it remained to serve the purpose of acting as a hollow diplomatic threat of a two-front war if Germany pursued an aggressive foreign policy. Most of the Locarno powers felt that the pact would act only as a means of dragging them into a suicidal war with Germany for the Soviets' benefit.

The pact marked a large-scale shift in Soviet policy in the Seventh Congress of the Comintern from a pro-revisionist stance against the Treaty of Versailles to a more western-oriented foreign policy, as had been championed by Litvinov.
