no, elite AI is supposed be similar to real wolrd, or at least not brain dead like regular AI, so if in all your match you invade a country without declaring war first the AI knows that(there is a hidden stat in your account that also delay the amount of time the AI gives you row and peace) and at first it embargos you, then declare war on you...starting with your closest neighbor.
i dont think the AI decision making on declaring is with a purpose(IE: its random) so lucky you luxemburg declared first as a punishment war to try and stop you..... obviusly like real world if the punishing army get whipe the rest of the world would still give you even more stink eye
