Joining the Axis? Interesting, I recently began a new game. I'm freedom-ed myself to a Integralist governament in the beginning of the game, in part to get rid of Getulio "Not Left-Wing Radical" Vargas and his IC blackhole. I shifted Brazil to a Centralized Economy, a more hawkish policy, closed the society, turned the governament to Facist (but somewhat far away from National Socialist, as the Integralists were facists but they believed in the Unity of all races, only one of them was a racist) and gave them one more intervention point. Its 1942 and I already took Venezuela and Bolivia. As soon as I get a decent army all up and running, I'm going to join the Axis, take over the Guyana and british carribean islands, then DoW Argentina and run over them with my tanks. Then puppet Chile, take Colombia and Equador.
The idea of teaming up with Argentina and joining the Axis interests me. As long as Argentina agrees that Venezuela should be a Brazilian puppet, that is. I can share some oil for tanks and ships, in exchange for resources I don't have and for a good price. (Brazil is strangely metal-poor in HOI2, WTF?!)
Off-Topic: Puppets give me ALL their resources after their stocks reach 1000, right?
