If Axis Germany won the war, how might their military evolve?

Bomb finished in 5-10 years so 1947. The destroying of factories and liberation caused a slow down. Also the U2 rocket would be a german invention and the space race would not happen(captured scientists helped in both contries in these projects). In addition, the USSR would be gone (Germany and Japan were originally in talks for cooperation until there were issues(this bond is due to the Dutch durring the 1600's and the involvement of germany in this trade)). In addition, Vichy France would be under German control. German allies would be Japan, Mexico, Brazil(possibly), and any South American country with an issue with the USA like Cuba(I know it is not in SA). In addition, China is gone and Germany has half of Russia, halfway down Asia(at that point), and all of Africa. with the rest of Asia and all of Alaska to Japan with possibly a SA country like Brazil having the entire continent. The USA and Canada would be alone against Germany and Japan along with separatist groups. Luffawaffe would be perfectly fine only way stronger and the Army and Navy have the same growth. There would still be conflicts with land but not until the land is expanded too much (2100).
