I want to know the answer to the following question:
How many civilians were the Japanese hoping to kill during their planned attack on San Diego?
All the background I'm provided with is that "The plan was called "Operation Cherry Blossoms at Night" and called for kamikaze planes filled with fleas infected with plague (Yersinia pestis) to crash into civilian population centers in the city, hoping to spread plague in the city and effectively kill tens of thousands of civilians.". Is that enough to answer the question?
Answer: yes
