and Hitler does not die in 1945 in this timeline (however you may make it). make it more like 1965-1980 when he dies. k
good luck
This bit isn't possible. Hitler had late stage Parkinsons (or some other disease of the sort) by 1945, and certainly isn't going to survive the 50s, perhaps not even the 40s.
Also, some of you're borders are far to convergent. Hitler wanted to annex Ukraine, but he didn't want colonies, or Russia east of Siberia. South Africa may have been brutally racist, but they hated the Nazis, and as apparently Britain and Australia aren't part of the Nazi Empire, there's no way that South Africa will be, particularly as isolated as they are.
Equally, the Nazis had effectively zilch capacity for landing troops in the Americas- the only friendly land there was Vichy France held Guiane- and with that being America's back yard, you're not going to have places like Cuba ruled directly by such a hostile power. Puppet status is unlikely as well, given that the Nazis don't really have an ideaology that the Cubans or Guyanans will find attractive.
Turning to America, North Korea only is bonkers, that border is simply a ceasfire line in a Civil War. If the North is held by America, so will the south. And if they've got Korea, they'll have the Philippines as well for sure which seems an odd ommision from the map.
I would suggest you go over to Books and media. There's a whole thread of maps showing what Hitler actually wanted.
