For the simple reason that they have turned their backs to the revelations of God, and have gone so far as to kill the Lord’s Prophets, they are cursed by God. Consequently, they will be disgraced and humiliated whenever they face you unless they uphold God’s covenant as well as respect their peace treaty with you. A little bit security that they may enjoy is not earned by them but has been the result of the help and kindness of others (American help in case of Israel, for instance.)
