Reichsmarine war planning in the 1920s

How could the Reichsmarine have fought a war in the 1920s or delayed defeat?

Torpedo boats, supported by a few pre-dreadnoughts and other limited assets, offered the principal means of resistance, with little prospect of a secure advantage in this assessment.

Torpedo boats receive most of the weight in this brief assessment of the Reichsmarine's wartime options. A few pre-dreadnoughts and other assets would offer limited support. The phrase 'torpedo boats and prayer' conveys the weakness of that position. The exchange gives no detailed operational plan or confident means of avoiding defeat.
