Updating the Historical ww2 map

The historical ww2 map is supposed to be a historically accurate map but its not.

1 Iraq owns Kuwait but the UK historically did

2 Macau isnt owned by Portugal but it historically was

3 The USA does not own the Panama Canal but historically did

These are just a few of many inaccuracies on the map but the most noticeable. Could these please be changed to make the map even more historically accurate. Thank you
