So I've been playing as Vichy France at the eastern coast of Asia (using the random scenario mod) and I've just defeated Argentina in a war. However, they joined the Axis shortly after they declared war on me, and their surrender caused them to go into exile. It's quite annoying because the land that I annexed only gives me around 50% of the IC it actually supports on the strictest occupation. I decided to try to conquer where they are exiled, but they are exiled in the southern tip of South America, and there is no island in the Pacific Ocean that I could possibly capture that would be in naval range to land an invasion there. This has been my first serious game and I'm so far only familiar with land techs. Is there any techs or other ways in which I can increase my naval range or is there just any way in which I can land an invasion force there? Also is it possible to defeat a country in exile without having to defeat the entire faction, because the faction leader is the U.S.A. and they control almost all of South America and Mexico. I doubt I could defeat their 500 brigade army and get past their vast navy...
Also one more question. I allied with my neighbor, the Dominican Republic because I was too weak when I first started off to actually conquer anything, and currently our private alliance is at war with Tibet. I've been hoping to annex the Dominicans because they are the only thing blocking me from the largest portion of land that I have conquered. It gets quite annoying having to ferry divisions and waiting months for them to actually travel through the frozen land where if I just conquered them I can deploy my units on my border instantly. Now Tibet is a problem because they have been at war with me and the Dominicans for over 2 years now and all that is happening is that the Dominicans and the Tibetans have just piled large piles of divisions onto the small border they share and it is just a complete stalemate. Nothing is happening and I can't break my alliance with the Dominicans because of this. That means that I cannot actually declare war on them and secure their land. Is there any way to break this alliance relatively easily, and if not, how would I edit the game files to do this?
