What if at he conference the Russian in December 1915 say we can't do offensives next year. We need a year off to recover, the Murmansk railway needs completed to import supplies (completed March 1917 OTL), offensives can resume summer 1917.
These means no Lake Naroch or Brusilov offensives in 1916?
What are the effects:
a) Can the Russian Monarchy survive?
b) What are impact on Italian and Western fronts?
c) Impact on Romanian entry?
d) Impact on German leadership?
