the unification of a hemisphere
I've always thought the Americas are similar to Europe, the '' Union of the Americas '' could emerge similar to the European Union model. Here are some features in this alternative union that I'm looking for:
- the alternative union must have a single currency and this currency can not be the US dollar
- have open frontiers between the members and the passport have written in them '' union of the americas ''
- This nation can coexist with the other blocks of our timeline, but it must be the most powerful union
- All members are sovereign states
POD may be at any time, but preferably after WW2. I'm not asking you to write a timeline. I just want to have a discussion if the American Union can exist. The probable candidates, I think, would be the Spanish America unified and the united states annex the canada and the brazil remains an empire thus creating a balance in the americas with 3 great powers leading to the union of americas.
Another would be Brazil restores the monarchy and with the passage of time becomes the second largest western power after the USA and other infinite possibilities.
