I’m actually curious what US strategies everyone employs for KJF that does not condemn Moscow to falling. Which I think is the heart of what the OP was getting at.
I typically spend US1 and US2 purchases entirely on the Pacific and then invest 100% in the Atlantic for multiple rounds.
I’ve tried the 80/20 or 70/30 approach, but it seems to take longer to really get involved in any significant way in either theater. Time is something the Allies do not have if they wish to save Moscow and/or Calcutta.
I’ve also found it is almost a waste of time trying to shuck anything less than 30 Allied ground units into Europe if you think you’re going to hold what you took. If Italy is spending on Inf/Art from the get go, Italy has a solid stack of units by the time the US can make a landing - which will easily push small Allied landings out of Europe.
To me, it seems only when you dedicate yourself to landing and holding it - which generally requires the full US income to accomplish, are you able to take Normandy and deter or withstand an 1-2 Italian and German punch.
If you cannot hold the territory you took, the time it takes to get that large of a stack back to try again is enough time for the Axis to rebuild themselves - and leaves Moscow for the crows.
So, what are you all doing that you are able to save Moscow and keep a competent Japan player negated?
