this is not surprising at all, if there are 3 counties that can invade them than that is obviously gonna happen, does 2 next to Annan and maybe 1 country from overseas (In my opinion that would be what silver-hand would do if they are smart) MC shouldn't have choicen japan, there is no gain for him doing so, he should choice Mongolia having them fight his opponent and when japan invalid they would use the players as MC takes care of other invaders. also if those 2 next to Annan invades its not that bad, one of them have only 800 000 the other something around 1 000 000 combat players, so he can take care of them before invading to take out the capitals :/ defending is easier then invading after all :P
