So I have one of these silly protectorates in Asia. I always thought protectorates can't have allies - at leas that's what the toolbox said when I created the protectorate. Anyways, so Champa, my protectorate, is allied with Benga, Sukothai and Ming. I am planing on declaring war on Bengal next. They are allied with Punjab and Champa. If Champa joins the war with Bengal then Champa becomes war leader against their overlord. Then they would most likely call in Ming who then becomes war leader..
