So I was playing as a peacefull Mexico, when USA suddenly declared war. So I scrambled my 3 semi mobilized divisions to hold off the horde and when I had to retreat (I actually won with my dug in 19000 troops against 50000 the first few rounds) I noticed in my relations screen, that I was in a colonial war with USA, and thus enjoyed, not caring for those stupid colonies in the north, I just waited for a peace offer (knowing that my normal provinces could not be claimed in a colonial war). And the time came and USA merrily suggested I give up 1/5 of my NORMAL provinces (that they had occupied) and only one colonial!
What gives....???
