It was pretty obvious where I was heading, y'know with my huge military build-up. I was going to declare war on Argentina, get the USA dragged into the war, and possibly the Incans. I was going to do a pretty complicated campaign to take Buenos Aires, knocking him out. After that turn had ended and my army had healed, I was going to head west and knock out Chile, then move North, annexing the both of them.
After that, it would've been a push northwards, to take American bases and governments with American influence.
This was going to be a pretty damn fun turn.
