Until you realize that interference with the “timeline” means many of the battles never happen
Sure, but that would be the point actually. If you had the kind of complete information about the Axis military deployment and resources in 1941 that this scenario would provide, you wouldn’t apply that information willy-nilly, one battle at a time. You would plan a complete campaign to disable the military systems of Germany and Japan all at once, and bide your time until you could implement it.
You would know where every major resource storage is, every production facility, every training facility, every unit deployment, every command headquarters - and the enemy wouldn’t know that you know that yet. You would just fully decapitate the command and logistics of the Axis all at once. Any remaining battles would just be a cleanup operation - they can’t run tanks, airplanes or ships if we wipe out all of their fuel storage and production because we know where all of it is (or was) in 1941. And because you have the Pentagon staff, you have capable people who could actually plan and organize such an operation.
new tactics can be countered
Eventually, maybe, but if you planned your operations right there simply wouldn’t be time. The point isn’t to win battles, it’s to take away the enemy’s ability to start a battle.
modern logistics require strong communications
This is true, and the communication options are limited by the time, but we’re not talking about trying to replace the Allies’ existing logistics infrastructure. We’re talking about using what the Allies already have, with perfect knowledge of what the Axis has when and where, and then picking the right moment to disable their military infrastructure across the board.
