I've found out how to add that text so it appears in the game
(add to the text.csv file under USA_DESC and delete the line desc = "" from the scenario.eug file).
However, it seems like you can't have paragraph breaks; if you insert a return, the screen only shows the text up to that point and nothing afterwards. So all country descriptions will have to be written as a single big paragraph - which probably means we should try and keep them short! This USA one covers three and a half screens of text, incidentally.
The same goes for event text added to the text.csv file - it has to be formatted as a single unbroken paragraph.
