The angels and the archangels will help you with world peace to the degree it affects you. But they have to honor everyone's free will - including the will of people who like to use weapons or to give orders to soldiers. They cannot usurp such people's free will. Say to the angels, "I affirm or ask for world peace to the degree it affects me." Think of the world as an array of intersecting circles. The part of the world with the intersecting circle that has you in it is what the angels can and will help with.
