Argentina has taken action to secretly remove the current government of Paraguay because it poses a danger to her northern border. It also looks to the danger of Brazil's border moving further south.
The Argentines want it made clear that any attempts to intefere will not be looked kindly upon. By any other nation. My ultimate aim is annexation in the form of a mutual desire for union with Argentina. It benefits both nations, they get a democratic government, jobs and reconstruction (open to foreign investors so all WW nations can make money) and Argentina gets a more land and resources. After all we are liberating Paraguay, who will invite us to help them, not like Chile Vs Bolivia.
Mexico need not bother about the Catholic rebels, their resuced leader is an Argentine puppet, they can be dealt with later...
