I want to know the answer to the following question:
How long was the secret agreement between Germany and the Soviets?
All the background I'm provided with is that "On 24 August a 10-year non-aggression pact was signed with provisions that included: consultation, arbitration if either party disagreed, neutrality if either went to war against a third power, no membership of a group "which is directly or indirectly aimed at the other".". Is that enough to answer the question?
Answer: yes
