Beh Judàs Iscariotes, didn't expect this in the morning, or at all really. Surprised
@Agent23 remembers I am both. SO :
1) Assuming Brazil is hostile to NATO forces, Italy gets help from US and UK and France but the third is more likely because we had multiple spats with the Parisian elite over the Franco-Guyanese (they tried to fund a separatist nativist republic and failed miserably). The Brazilian military might turn on the government (assuming it is a lefty one) and the war is over before it even starts.
2) I don't know if there is even a possibility of ISOTED Brazil to reach Italy or the colonies which are in North Africa and East Africa. Before going to war, the Brasilia government has to somehow convince the armed forces and the populace it is worth to die for Ethiopia, Somalia, Eritrea and Libya. Lula can convince his electorate, the current army heads even though they are traitorous swine are probably going to ask him how much cachaça he drunk for this dumb idea.
3) You would have to somehow turn Getulio Vargas (a Lula-prototype but socially conservative if you ask some people) a pro-Axis-business fella that the fucking effort is worth it, same thing goes for Italy leadership. Brazil can't win unless in its own turf, because we didn't have the capabilities to reach the Mediterranean ALONE. The same can be said about Italy.
