No, it isn't. Hiroshima and Nagasaki were a case of one country attacking another. America attacking the civilians of Japan as an act of war. There is not another country "doing this" to America.
Americans are doing it to themselves. People who would put their own family at risk because they will not listen to scientists and doctors.
Have you looked at beaches? Have you seen all the people who have no problem being told to wear pants, but have a problem with masks.
No. If another country was doing this "to" America, maybe it would be American's Hiroshima. But Americans are doing this to fellow Americans. It's like that horror movie. The killer is calling from inside the house.
