[quote=@The Spectre]If I have decided to stay in Central America, then I would be in a weak state. And that would give Mexico and/or Colombia reason to attack and take land.[/quote]

This isn't EU4 or Civilization or something. Mexico and Colombia aren't just going to randomly attack you and take land for no logical reason other than simple expansion, for the same reason that Mexico and Colombia don't do that in real life. Mexico hasn't fought a war with an external power since 1867, and Colombia since 1933 (and that war ended with no transfer of territory).

Even if a player does take over, I consider the likelihood of them actually consistently IC posting fairly low. There's a reason South America was considered the Bermuda Triangle of players last RP.
