What if the League of Blood assassins had killed everyone on their 1930s target list?
Short answerThe likely result is a Japanese civil war because the victims included stabilizing leaders and the killings would trigger resistance from powerful political and social networks.
NotesThe proposed assassination campaign includes figures whose survival is considered important to the Japanese state's stability, with Mitsumasa Yonai singled out. Killing all the targets would collide with the interests of political, imperial and underworld networks. Civil war and institutional breakdown are predicted in this counterfactual. Retaliation could also reach the fleet through interrupted supplies or deliberately poor-quality provisions. These are proposed mechanisms within the scenario, not claims that the complete campaign or its consequences occurred.
