What do you suggest is the correct response to losing territory/lands/homes where you havent attacked your neighbour? Where your neighbour just moves in and takes your home and pushes you out Cuckoo style knowing you have the backing of a better military as backup/intimidation?

@Twinz - It would be like the USA expanding into Mexico or Canada and just spreading out, displacing the Mexican population knowing there is nothing they can really do about it (NATO implications aside for Canada example)
